Classic Kansas City Barbecue Sauce

This Kansas City sauce is a little sweeter and, with the addition of butter, a little more round in flavor.

1/2 cup firmly packed dark brown sugar
1 Tbs. onion salt
1-1/2 tsp. celery seeds
1-1/2 tsp. garlic powder
1-1/2 tsp. chili powder
1 tsp. finely ground black pepper
1 tsp. ground cumin
1/2 tsp. cayenne
2 cups tomato ketchup
1/4 cup white vinegar; more to taste
2 Tbs. prepared yellow mustard
1 tsp. fresh lemon juice
1 tsp. liquid smoke (optional)
4 Tbs. butter, cubed and chilled

In a medium saucepan, combine all the ingredients except the butter. Bring to a boil, stirring to dissolve the sugar. (You may want to have a lid handy to protect yourself and your kitchen from any sputtering.) Reduce the heat and simmer for 25 minutes, stirring occasionally. With a whisk, blend in the butter cubes, a couple at a time, until incorporated.

Yields about 3 cups.
