Received this recipe from my MIL for pulled pork. It is so good. The lemon flavour really comes through the day after it is made...Loved it with pulled pork, think it would be good on any pork or chicken.
Combine the ketchup, brown sugar, lemon zest and juice, molasses, Worcestershire sauce, liquid smoke, mustard, onion powder and pepper in a non-reactive saucepan and whisk to mix.
Gradually bring the sauce to a simmer over medium heat and let simmer until thick and flavourful, 8-10 minutes. Taste for seasoning, adding more lemon juice if necessary. Transfer the sauce to a bowl or clean jars and let cool to room temperature. Refrigerate the sauce, covered, until serving time; let it return to room temperature before using. The sauce can be refrigerated, covered, for several weeks. Makes about 3 cups.
