Preheat the oven to 150°C and place a heavy-based, shallow saucepan on the heat.

Add the oil and caramelise the diced beef cheek over a high heat. Add the onion, garlic, chilli and red pepper, reduce the heat and caramelise 5 minutes before adding the spices. Once sticking and going dark, add the tomato paste, vinegar and beer and scrape the base. Add the chopped tomato and kidney beans, lid on, and cook 2 hours until the cheek is soft.

Press the beef with a fork to a compote texture, adjust the seasoning and set aside. Increase the oven to 220°C.

Peel the potatoes, add to a pot with 3 litres water and 30g salt, boil then simmer 10 minutes until starting to fall apart. Drain and cover to dry.

Heat a large non-stick pan with the beef dripping, fry the potatoes and garlic until crispy, then roast at 220°C, tossing regularly, until really crispy.

Mix the taco sauce ingredients.
