I don't like traditional red barbecue sauce, but I love the white barbecue sauce on tofu (because I don't eat meat). We have always called it Firemen's Barbecue Sauce because every year the fire department in my home town of Cuba, NY has a chicken barbecue and they use the white sauce. So no matter whether the sauce comes from the bottle or is homemade, it's Firemen's Barbecue Sauce to us!
I don't know what the exact recipe is, but the main ingredients and approximate measurements are:
1 c. olive oil
2 c. cider vinegar
2 tbsp. salt
1 tbsp. poultry seasoning
1 tsp. pepper
It works best to make it in a blender--put the egg in the blender and blend for a second, then add the oil and blend it good. Slowly add the other ingredients and mix it up. It will separate when it sits, so you'll need to shake it before you use it. Put it on whatever you normally put barbecue sauce on. I like to put tofu in a pie pan and dump some of the sauce on it, then put it on the grill. Delicious!
