Place all the ingredients except the olive oil in a food processor. Pour in the oil slowly through the funnel in the top. You should have a sludgy, vibrant green sauce. Set aside until ready to use.
To make the horseradish cream
Place the grated horseradish into a bowl and pour over the red wine vinegar. Season with salt. Stir in the creme fraîche and place in the fridge until ready to use.
Place a large pot of well salted water on to boil. Trim the woody ends of the asparagus.
To make the lamb
Lay the lamb cutlets on a board. Season generously with salt and freshly ground black pepper and brush with oil. Heat the barbecue or a griddle pan until smoking, and cook the cutlets for 1-2 mins per side.
While the cutlets are cooking blanch the asparagus by dropping it into the boiling, well salted water. Cook for 40 seconds - it should still have a nice bite. Alternatively, griddle on the barbecue alongside the meat.
Remove the cutlets from the grill and squeeze over the lemon juice. Let rest for a few minutes to allow the meat to relax.
This is a real star of a dish so invest in the prep so you can simply griddle the lamb and serve on the day.
Arrange the cutlets and asparagus on a serving plate, spoon over the salsa verde and serve the horseradish cream alongside.
“Make sure your meat is room temperature before you cook it - meat cooked straight from the fridge will take a lot longer.“It’s really important to allow meat to rest once it is cooked - it will have a much better textures and flavour.“The horseradish cream can be made the day before but salsa verde is best made on the day of eating as the herbs will keep their flavour a lot better.“Both Horseradish cream and salsa verde are incredibly versatile and can be used to brighten and flavour vegetables, fish and meat.”Andrew Peace Wine pairings“Choose a red that works in summer and well placed for lamb; The Unexpected Red is an offbeat blend of three classics; Cabernet Sauvignon, Merlot and Tempranillo with Sagrantino, which work together to create a smooth and full-bodied wine that is a rich, deep blood-red garnet colour with flavours of blackcurrant, bright cherry and hints of spice and violet.
