Z as with most of my 'recipes' I don't have exact amounts. I throw things together and take lots of test bites.
Saute some diced onion and garlic in olive oil. Saute until the onion is good and soft but not brown.
Stir in 1 cup catsup
4 tablespoons brown sugar ( more if you like it sweeter)
2 tablespoon yellow mustard
2 tablespoon water
3 teaspoons Worcestershire sauce
crushed red pepper to taste. ( Sometimes I don't add any)
Simmer for 5 minutes. Use on beef, pork or chicken. It's too overpowering for lamb or fish. This sauce seems to last in the fridg. for a long time. This is a very easy recipe to make to your taste. Just add more of the things you like and less of those you don't.
