This is where having a Vitamix at the ready really comes in handy, although a lesser mixer will probably do the trick, just not quite as smoothly.
1 medium white onion, chopped
About 6 ribs of celery, coarsely chopped
3 cloves of garlic, crushed before putting in blender
1 tablespoon coconut oil or olive oil
2 small potatoes, peeled and chopped
1 teaspoon of salt
dash of hot sauce (I use Frank’s)
Sauté onion, celery, garlic and potato in oil until soft, taking care not to use too high a heat that might result in browning. Put the equivalent of 2 cups of water in crushed ice in your blender, and add your finished, sautéed mixture. Blend until smooth and serve. Add a little more chilled water if the end result isn’t liquid enough, stirring thoroughly.
