100g caster sugar

35g butter

1 clove garlic, crushed

100g peeled, grated horseradish

100g purple carrot

100g orange carrot

100g white carrot

100ml rapeseed oil (or green parsley oil)

For the coriander and thyme salt

1tbs coriander seeds, toasted and blitzed

1tbs of picked thyme leaves (save the stalks to add to the caramel)

3 egg yolks

20g Dijon mustard

15ml sherry vinegar

10ml honey

100ml oil

Set up a charcoal grill well in advance so that the coals are glowing red-hot for searing the beef. (You could also use a very hot grill pan on the stove.)

Pre-heat the oven to 180°C. Trim the beef flank, keeping all the trimmings. Roast the trimmings in the oven for 25 minutes and reserve the drippings for the emulsion. If the flank is too lean, buy drippings from your butcher.

Meanwhile, make the coriander and thyme salt by mixing together the coriander, thyme leaves and salt.

Season the steak well with the coriander and thyme salt and a kiss of oil. Sear really well on the very hot charcoal grill. Chill as soon as it’s off the heat by putting it in the fridge uncovered. This will stop the cooking process.

Make the beef dripping emulsion by whizzing together the egg yolks, mustard, vinegar and honey in the small bowl of a food processor, then gradually adding the oil to make a thick mayo. Then add the dripping and water and whizz until thick and smooth. Season to taste and put into a squeezy bottle or a piping bag.

Make the horseradish caramel by melting the sugar in a dry pan and cooking it to golden bronze. Remove from the heat and quickly add the butter, then the garlic, thyme stalks and horseradish and stir through. Next add the veal stock, and put the caramel back on a low heat to cook for five minutes to help infuse. Finally, add the brandy and strain the caramel through a fine sieve.

Make the carrot salsa by finely slicing the carrots into rounds on a mandolin or with a very sharp knife. Add the oil, vinegar and rapeseeds and finish with the parsley.

To serve, shave or very finely slice the beef against the grain of the muscle with the sharpest knife in your kitchen. Cutting against the grain achieves tenderness. Arrange the beef shavings to cover the surface of the plate, drizzle with the caramel and randomly spoon on the carrot salsa. Finish with dollops of dripping emulsion.

Garnish with tarragon leaves to give a bit of height to the plate.
