The Cambridge Menu

The brief from BBC Radio Cambridgeshire was simple: create a dish that sums up the area using the best locally sourced produce available.



Cornwall has the pasty, Bedfordshire’s got a clanger and Bury the black pudding – but Cambridge? Cambridge has…well, therein lay the problem. Our county is bereft of a classic.

The challenge to rectify this glaring omission came from our local BBC radio station. I would have a week to come up with something special and they’d then record me creating it in my own kitchen.

The obvious place to begin was looking at what local produce was available. It soon became clear that the area may be lacking in a signature dish but that isn’t for want of superb ingredients: locally reared beef, pork, lamb and game are plentiful, when in season.



In May, the Fens groan under the weight of the asparagus spears that peep through the earth. Celery and watercress also grow in plentiful abundance. The committed and enthusiastic loca-vore can even take their rod and line down to the River Cam and try to land a pike or zander. However, I didn’t think a week would be enough to organise a fishing licence (or actually learn how to fish).

Being bound to the fruits of the local land was no hardship, though and after a few days of hard research I came up with the following efforts for my Cambridgeshire Feast. Great British Menu, watch out.

Starter: Asparagus, bacon and egg



With it just sneaking into season, now is a great time to eat locally grown asparagus. The spears are sweet and tender and are yet to develop the slightly woody note that can tarnish the fern later in the year.

This isn’t a very original presentation but my goal was to keep it simple. The asparagus was steamed, brushed with butter then served with an egg (from our front garden) poached at 64˚and a couple of slices of home-cured pork jowl, uniquely preserved by the Cambridgeshire air and then fried until crispy like dry-cured streaky bacon.

Main Course: Beef cheeks, braised celery and Stilton and mustard cream




Beef and Stilton is a classic combination. Stilton and celery, likewise. Here they come together in a wonderful open pie.

Whilst most regions in Britain can lay claim to a local cheese, Cambridgeshire’s most famous dairy product can’t actually be made in the county. The PDO that proudly adorns Stilton cheese limits its production to the three counties of Derbyshire, Leicestershire and Nottinghamshire – but the town of Stilton itself lies within the boundaries of modern-day Cambridgeshire and here is where the cheese became justifiably famous.

Beef cheeks (from CamCattle, a company who locally rear cattle grazed on common land in the centre of Cambridge) were cooked slowly in red wine and stock with carrot, celery, onions and garlic until tender – then the cooking liquor reduced to a rich and sticky gravy.

The celery too, was braised by browning in a little butter then covering with a light chicken stock before being vacuum sealed and cooked for 35 minutes at 85˚ (the temperature at which pectin – the ‘glue’ that holds vegetables together –breaks down, making vegetables tender but ensuring they retain a little bite).



The celery and beef were topped with a disc of puff pastry and then a cool cream flavoured with Stilton and mustard was added to the dish, along with a some watercress for a peppery bite.

It may be a little optimistic to hope it’s a future classic, but one can always hope. It’s certainly delicious enough to warrant making again, very soon.

Dessert: Cambridge Burnt Cream with Rhubarb

Perhaps better known as crème brulee, this dessert was the closest that I came to finding a genuine heritage dish from Cambridge. Although the veracity of the origins of the dessert cannot be verified, legend has it that it was first served at Trinity College in the late 19th Century – a tale that Ian Reinhardt, head of catering at Trinity, was happy to stick to. As am I.



Rhubarb seemed a natural addition – both because it can be found all over the region at this time of year and also due to its natural affinity to custard: a pairing that almost universally tends to remind us of childhood.

Deceptively simple, the secret to a perfect ‘Burnt Cream’ lies in setting the custard to a soft texture without scrambling the egg yolk. Just don’t get it too hot.

Split a vanilla pod and add the seeds to 425ml double cream and gently bring to the boil. Whisk together 110g caster sugar with four egg yolks until pale then pour the cream over the yolks and sugar. Return to the heat and bring almost (but not quite) to the boil.

Pour the custard into ramekins and cook in a low oven (or bain marie) until set. Chill then sprinkle the tops with sugar. Use a blowtorch or hot grill to caramelise the sugar then cool.

For the rhubarb, melt 25g butter and 25g sugar in a pan. Add the sliced rhubarb then cover with orange juice. Cook until the rhubarb is tender (about 7-8 minutes), remove and reduce the liquid to a glaze to spoon over the soft rhubarb.



One final flourish that Ian kindly shared with me when I went to speak to him about the origins of this tasty pudding concerned the ‘branding’ of the caramelised sugar with a metal plate adorned with the college crest. A piece of theatre indeed, but perhaps a little extravagant for the home cook – at least, until I get my own coat of arms commissioned.

So – thoughts? Feedback? Outrage that I’ve missed a truly local classic? Get in touch in the comments or on Twitter and we’ll have a chat about it.

Celebration Steak

As weeks go, the last seven days have been quite surreal.

There’s not much that can prepare you for making your debut on national television. It’s a little like getting onto a rollercoaster in the dark with no clue as to how the ride will pan out.

Thankfully, there have been no major hiccoughs. The heats and quarterfinals have been safely navigated and I’ve come out the other side as a MasterChef semi-finalist. It’s truly wonderful to be able to write those words.

The response has also been fantastic and genuinely heart warming. Thank you to everyone who has phoned, written, texted, emailed, tweeted or shouted across a car park. Thanks even to the person who suggested I might be Chris Martin and Stephen Merchant’s offspring (but only because you’re a Radio 1 DJ).

But my favourite response has been this:



It was quite a surprise when we pulled up in the car park at the butcher/farm shop/deli/food nerd’s nirvana that I go to and saw that sign, usually reserved for far more important matters like proclaiming the arrival of the season’s first rhubarb or new potatoes.

We were there to pick up a meal worthy of a celebration - and to my mind few things shout ‘hooray’ better than a whopping great steak. Whilst individual pieces are all well and good, practicality, economy and taste favour a shared piece of beef, especially if cooked rare and sliced tableside.

A hearty single rib (côte de boeuf if you wish to get all Gallic about it) from a Red Poll raised a mere four miles away was ideal. Aged just over four weeks the meat was dark red and looked tender enough to eat as was. Instead it was liberally seasoned, vacuum packed and submerged in a water bath to bob around merrily for a couple of hours at 52 degrees.



The logistics of the operation presented some slight problems: on realising that my largest pan was not big enough the bone had to be trimmed away and the rib-eye seared on both sides for about five minutes in order to put a tasty crust on the outside.



It was served with chips, an artery-clogging amount of béarnaise sauce and a heap of steamed broccoli as a concession to health - although once dipped into the rich buttery sauce the beneficial effects were possibly negated.



After waiting two and a half hours for a steak there was little that could have prevented us from falling on it like a pack of wolves hence the distinct lack of well composed, perfectly lit photographs.

In this case the lack of picture says a thousand words.

The MasterChef quarter final can be found here, on the BBC iPlayer and the first of the semi finals will be broadcast on BBC1 on Friday 26th March at 7:30pm.

And I'm also on Twitter.

Five hour steak

The perfectly cooked steak is the holy grail of many chefs and home cooks.



For me a steak is a treat, a rare (no pun intended) but glorious treat. As a result if I cut into one that is overdone the disappointment can easily ruin the entire meal and the next thirty minutes will be spent in a deep sulk that only time and some well-cooked chips can offset.

The happy inverse of that is slicing through a piece of beef that is cooked to the ideal doneness – a quivering pink throughout with a crisp, charred and heavily seasoned exterior. Oh, the sheer delight.

I can think of few other gustatory pleasures that can measure up to a perfectly cooked steak.



Fillet, for so long the posterboy of the steak world, doesn’t quite measure up for me.

It may be tender but its leanness is also its Achilles’ heel. For the fat is where the flavour is and a muscle that has done no work (its position in the anatomy of the cow ensures this is the case) hasn’t enough depth for the truly discerning steak lover.

Instead I prefer a muscle that has worked, one that has led a life of hardship and built up a rich marbling and intense flavour as a result. Give me an onglet or bavette to work my teeth into over a chateaubriand any day of the week.

The problem with these cuts is they can be a little too tough. Served beyond rare they turn into slabs of meat that could resole a rudeboy’s Doc Martens. Even cooked momentarily, with a brief kiss of a searingly hot frying pan, the presence of connective tissue and sinew can offer a mandible workout of intense proportions.

Enter the water bath – a way of cooking meat to perfection. Every. Single. Time.

High end restaurants have long known about the benefits of cooking sous vide. Four or five years ago I ate a piece of lamb at Midsummer House, a two-star restaurant in Cambridge. It was delightfully tender and so flavourful I can still recall it now. I couldn’t quite believe it when I was told it had cooked for six hours. How was it still so pink inside? And uniformly so?

Thomas Keller is such a convert that he has written an entire book about the method. More top shelf gastro porn from the author of The French Laundry Cookbook and Bouchon.

I’d looked into buying the kit (called immersion circulators) to achieve the results at home but they were bulky and astronomically expensive – designed for commercial kitchens rather than the shoebox I have at home.

But then a couple of weeks ago I was sent one aimed at home cooks from these guys. It’s small, easy to use and delivers results you would expect in top restaurants.

And as someone who delights in the science of cooking and the potential of gastronomic experimentation, it is fast becoming my new favourite toy.

For beef junkies, skirt steak is the ideal cut. It’s incredibly tasty and bargain basement cheap. Cooked right it’s a joy to eat but its window of deliciousness is small. In other words, the perfect guinea pig for my first forays into sous vide.



Each piece was well seasoned with black pepper and sea salt then placed into a plastic zip-lock bag. Apparently sous-vide means ‘under vacuum’ so enter the vacuum cleaner. I sucked out as much air as I could then quickly sealed the top before dropping the whole lot into a stockpot full of water at 52 degrees.

Why 52? 50-60 degrees is the temperature window at which the meat proteins co-agulate, or cook. Pick a point between these two magic numbers and your steak will be between rare and medium rare and gloriously juicy.

And there it remained for five hours, bobbing up and down and gradually turning an unappetising shade of grey-brown before being removed and shocked in an ice bath to stop the cooking process.

A frying pan was heated to ‘scorching’ and a small drizzle of cooking oil – enough to cover the bottom – was poured in. Whilst it was coming up to temperature, the steak was seasoned again then cooked on either side for about a minute until a generously dark colour covered each side.



After a five minute rest on a warmed plate it was time to cut and see if experiment one had worked:



What surprised me most was the uniformity of the cooking. The meat was at the rarer end of medium rare all the way through. There was no gradation towards a pinker centre but the same colour throughout, aside from the dark brown crunch of the exterior.

The flavour was assuredly beefy, intense and unmistakably steak like. The outside crisp, rich and earthy and the interior almost sweetly bovine and wonderfully soft. Whilst the meat could have been slightly tenderer – which could be achieved over a longer cooking period – it offered enough resistance to be satisfyingly chewy.

It was, easily, one of the best pieces of meat I’ve ever tasted. From now on, for me, there is only one way to cook steak. Now, I wonder if pork belly will work…?
