Method
Step 1
Put a dry griddle/frying pan on high heat. On a chopping board rub both sides of each lamb cutlet with salt, pepper and olive oil. Place cutlets in hot pan and sear for 3 minutes either side until golden and still pink in the middle. Adjust time to suit your preference. Important – only turn cutlets once using tongs (or spoons). Cutlets should not overlap. When done, remove and set aside on a plate covered with tin foil to rest for about 10 minutes.
Step 2
Place brussels sprouts in a saucepan with a small amount of lightly salted water. Cover and steam for about 10 minutes until tender (but still a little crunchy). Combine butter, yellow mustard powder, lemon juice, dill, salt and pepper. Drain brussels sprouts. Add butter mixture and mix well. Keep warm.
Step 3
Add the beef stock, redcurrant jelly and any resting juices from the lamb cutlets to the pan (the one you used to cook the lamb cutlets). Simmer on medium heat for 5 minutes until syrupy. Add the wholegrain mustard, simmer for a few seconds more, and then season to taste.
Step 4
To serve, place the lamb cutlets and on the plate and cover with sauce. Add a serving of brussels sprouts on the side.
