Measure equal parts mustard and any red jelly of your choice into a saucepan or slow cooker. Give them a stir. You might be skeptical at first.
Warm over low heat, stirring occasionally. As the jelly melts the mixture will slowly begin to meld and you will have a smooth BBQ sauce in which to simmer your choice of meaty finger foods. *For sweeter sauce, increase the jelly by 1/4-1/2 cup.
