I got this recipe when we were at Edwards AF Base, out in the middle of the Mojave Desert in California, on our first Air Force assignment. I've been making it regularly ever since. It's always a big hit, served with an assortment of raw, fresh vegetables.
1 cup sour cream
6 Tbsp mayonnaise
2 Tbsp ketchup
1/2 tsp Worcestershire sauce
!/2 tsp curry powder, at least
1/4 tsp cayenne pepper, less if desired
1 clove garlic finely minced [I use 2 or 3]
Mix all ingredients together and chill in refrigerator to allow flavours to blend.
The original recipe called for half of these proportions, but that would be like feeding buns to elephants, so....
