Spring Lamb Loin Chops with Pepper Sauce
1 tbspFinely Chopped Green, Red, Yellow and Black Pepper15 ml
1 tspFinely Chopped Jalapeno Pepper15 ml
8New Zealand Lamb Loin Chops8
Freshly Ground Pepper
1/2 cupWhite Wine Vinegar50 ml
2Shallots, Finely Chopped or Green Onions2
1/2 tspDried Basil2 ml
1/2 tspGrated Orange Rind2 ml
4 ozChilled Unsalted Butter125 g

Lightly sauté peppers in butter. Set aside and keep warm. Dry chops well. Sprinkle well with pepper. Grill or broil until just pink. Heat wine vinegar, white wine, shallots, basil and orange rind in a saucepan. Bring to a boil and cook until reduced to 3 tbsp. Whisk in butter, a bit at a time, until sauce is smooth and creamy. Season to taste. Place two chops centered on each plate. Spoon sauce around chops and sprinkle with peppers. Garnish chops with a sprig of mint.

You can pan fry them but hell not for 25 mins that is why they were tough.Cook them quickly until they are just cooked and still slightly pink in the middle but not bleeding.A bit like a med steak.4-5 mins on each sid should be enough depending on the thickness

I'm a sheep farmer and we eat lots of chops!I think they are best grilled in the oven, straight under a hot grill, for around 10 minutes.They are annoyingly expensive (and trust me, the grower isn't making money from them!) but seriously good.Better luck next time!

In the Oven 4 a start might help !!!
