Roast, Borough Market, London

Gamey, well-put-together venison burger

Burger source

There was beef wellington on the menu, but such is my commitment to burgers that – in realising that Roast – one of the defining meat-centric restaurants in London – had a burger on its Christmas menu – I changed my mind. Note this is a far cry from the Roast-To-Go burger I reviewed back in 2017, even if it was prepared in the same kitchen.

The order

So there it was – the Wild British Fallow Deer Venison burger. Featuring a brioche bun, stilton, beef tomato, lettuce and Roast’s burger sauce. Had to be done. We also had a healthy diversity of sides – pigs in blankets, garlic mushrooms, broccoli, cauliflower cheese and chunky truffle chips.

The meat of it

Let’s look at it again.

It’s well presented and constructed. Lettuce protecting the bun from a juicy (?) burger, good slice of pickle, bright, fresh veg, ‘Roast burger sauce’ on the side, and promising-looking chunky fries in the obligatory fancy tin pot.

Let’s come into the cross section:

Look at that colour! A perfect pink, absolutely amazing! And the light hasn’t helped but he brioche is quite pale beneath a warm and attractively grilled bun. You’ll also note that the bun has slipped off the giant lettuce leaves and doesn’t want to stay settled at all – I’m pro shredding the lettuce on the underside of a burger. This hasn’t stayed together as you’d hope, although I fully accept that most people don’t cross-section their burger in this way.

As to the taste – perfect seasoning, there’s a wonderful umani between the burger and the stilton – which is unobtrusive and subtle. The bun holds together well and doesn’t have the sweetness many brioche do; but has fantastic substance and bite, contrasting with its soft, fluffy blandness against the flavourbomb of the burger itself. The texture and mouthfeel is good, though the burger is a little dry overall – I suspect that wild fallow deer doesn’t have the fat content your average 20-30% beef burger patty might – and the light gamey taste adds a pleasant depth of flavour.

The Roast Sauce? Is basically just a fancy, smooth home made ketchup. It’s pleasant, but this burger wanted a mayo or aioli style burger sauce on the buns to add fat and moisture back into each bite. Pickle in there would have added good contrast to the dry, salty, gamey meat. Not bad, but a few refinements would have elevated it.

As to the chips – they were perfect. Double if not triple fried, crunchy on the outside and fluffy in the middle, they were perfectly seasoned and very flavourful. Again the ketchup/burger sauce was a good accompaniment, but would have preferred a mayo or aioli dip.

On the other sides (sorry for lack of pictures) – the pigs and blankets were just fine – good sausages but not desperately easily to distinguish from a pack you’d from Sainsbury’s. The mushrooms were extraordinary – the right answer to how much butter can you use when grilling mushrooms is ALL OF IT. I heard good reports for the truffle chips, the cauliflower cheese, the stuffing and more. Good all around.

Monkey finger rating

Bun –  4.5/5
Build – 4/5
Burger – 3.5/5
Taste –  3.5/5
Sides – 4.5/5
Value – 3.5/5 – £22 is a lot, although possibly reasonable given the venue and cost of the venison

Burger rating – 3.5/5 – Enjoyable and interesting novelty, though I probably wouldn’t have this again unless I could change up the recipe. The meat was just too lean for a burger patty, and there are a lot of other good things on the menu.

The deets

Wander around Borough market until you find the lift/steps that lead up to Roast. You can’t – no wait, you can easily miss it. Good luck and enjoy – let me know how you found it.

Roast to Go, Borough Market, London

Amazing crust, juicy middle, delicious burger sauce. Simple burger well executed.

The takeaway service of the very famous Borough Market institution, Roast, has a lot to live up to. I’ve not heard anyone experience Roast without singing its praises, though I’m yet to sample its wares in person… I will need to add it to the list. But, thanks to Uber Eats, it was an extremely efficient delivery option for a work burger lunch. The menu’s extremely limited, but Roast’s conceit is fine meat, finely prepared, finely cooked.

The order

The ‘Borough burger’ features a 30% fat 6oz meat patty, melted cheese, thick sliced pickle, tomato, lettuce and red onion on a semi-brioche bun.

The meat of it

Even delivered, this is a solid burger. Robust, yet somehow soft and inviting – a set of adjectives that only really makes sense when you’ve spent as much time thinking about burgers as I have.

And on first bite – wow. A crisp shell on the patty gives way to a juicy, perfectly medium patty; still inviting after the journey over on the bike, but not threatening the bun at all with dripping – this is not a messy burger.

The seasoning is savoury and inviting, the pickle sharp, sweet and a marvellous textural contrast. The salad accoutrements are a perfect, fresh complement to the savoury sensation the rest of the burger, and the semi-brioche adds a pliant hint of sweetness, not overwhelming, but holding the stack together perfectly. The burger sauce, largely mayonnaise, though clearly heavily accentuated, was sweet/salty perfection. It took an act of will not to eat this faster.

My only criticism – and it is hunting for flaws – is that the burger could possibly have been even juicier. But I suspect this is a factor of it being a takeaway rather than a flaw in the preparation.

I spotted that the recipe for this burger was in the wild as part of the promo for the Roast cookbook, so try to make it at home if you’re so inclined.
