Place 20 cloves of garlic in a pan and cover with half cold water and half full fat milk. Add a pinch of salt and sugar and the sprig of thyme.
Cut a round of greaseproof paper the size of the pan and butter one side. Place the round, butter side down in the pan to cover the garlic.
Place the pan on a high heat, bring to the boil and then reduce heat and simmer gently until the garlic is cooked through.
Remove the paper, strain off the liquid and allow the garlic to steam dry. When cool, peel off the outer skin of the garlic and cut out the germ of the garlic clove. Season with salt and pepper. Set aside.
Make the batter by mixing all batter ingredients together. Allow to stand for 20 minutes. Meanwhile to make the sauce: in another pan, add the white wine and the remaining garlic clove, crushed. Bring to the boil to remove the alcohol, then add the lamb stock and chicken stock. Bring back to the boil and let the liquid reduce by a third.
Add the double cream and bring back to a gentle simmer, reduce to a rich and creamy consistency. Adjust the seasoning and finish with a little lemon juice. Pass through a fine strainer or muslin into a clean pan and keep warm until required.
Preheat the oven to 200C/400F/Gas 6.
Heat a little oil and (clarified) butter in a pan. Season the lamb and then seal in pan on all sides.
Once sealed, place in a hot oven to roast for about 7-8 minutes. Remove from the oven and cover with foil and leave to rest in a hot place, like above the stove, for at least 20 minutes.
To make the garlic fritters: heat the oil for deep-frying in a pan. Dust the garlic cloves in a little flour and shake off the excess. Dip them into the beer batter and deep fry until golden and crisp. Drain on kitchen paper and drizzle with a little lemon juice and season with salt.
Cut the wild garlic leaves into squares and stir into the prepared sauce. Let the leaves wilt in the heat of the sauce.
Spoon the sauce onto plates spreading the garlic leaves evenly.
Cut the best ends into cutlets and lay cut side up on top of the sauce. Place five garlic fritters around the lamb and serve with seasonal vegetables of your choice.
