Roast Leg of Lamb
Tags:
To make this juicy leg of lamb, mix Worcestershire sauce, ketchup, mustard, garlic, rosemary and finely ground matzo meal (or flour if you don’t keep kosher). Spread over the lamb before roasting and it turns into a savory, delicious crust. Enjoy!
Please make any necessary adjustments for keeping kosher. The flour can be substituted with finely ground matzo meal. Be sure to use an OU Certified Worcestershire sauce.
