Homemade BBQ Sauce

I recently realized that I have never dedicated a post to my homemade BBQ sauce.  I've squeezed it in on a few other recipes, but this sauce really deserves more recognition than that.  With that in mind and BBQ season here I thought I better get to it and share this yummy sauce.  This glorious sauce that is so cheap & easy to make.  This sauce that I eat spoonfuls of before drowning some variety of delicious meat in.  This sauce that has converted me from any form of store bought bottled BBQ sauce.  This sauce that make chicken (or pork, or beef, or elk) taste better than ever.  You too need to experience "the sauce".  Make a double batch and have some in the freezer for dipping or a last minute BBQ chicken dinner.  Here's the skinny...
1 onion diced
3 Tablespoons butter
2 cups ketchup
1/3 cup molasses
1 teaspoon mustard
2 tsp brown sugar
1 Tablespoons Worcestershire sauce
1/8 cup whiskey
Melt butter in  medium saucepan.  Add diced onion & cook until tender, about 8-10 minutes.  Add remaining ingredients & allow to simmer stirring often for 20 minutes.  Taste it & add more salt or sugar as desired.  If you like things a little spicy add some chili powder.  So good you could eat it by the spoonful, but I suggest using it as a topping.  Makes about 2 1/4 cups.  Enjoy!
