This is my vegan/vegetarian recipe for sour cream. I like the taste better than commercial sour cream.
½ generous cup cashews or almonds, soaked, drained
½ cup extra virgin olive oil
½ cup water
2 Tbs. lemon juice
1 tsp. Real Salt
½ tsp. onion powder
¼ tsp. garlic powder
Blend all ingredients except lemon juice until nuts are completely pulverized. Add lemon juice and mix well.
