Wash beets well, being careful not to break their skins. Cut off the tops, leaving a stalk of about 1 1/2". Boil in a 3 quart saucepan until tender, covered. Allow the water to cool, then slip off the skins, trim off the tops, and cut into bite-sized pieces. Mix the remaining ingredients and pour over the beets. Let marinate for 1 hour before serving.
Beet Salad II: Prepare as described above, but add 1 tsp. orange flower water, 1/8 tsp. cumin, a pinch of paprika, and a little water to the sauce.
