Put almonds in the blender with enough water to come a little below the level of the almonds. Blend until completely smooth, adding more water and scraping down the cannister as necessary. When the puree is the consistency of pancake batter, add enough water to make it pourable.
Put mushrooms into a pan with the oil and saute until cooked and fairly dry. Add the almond milk and sherry, and cook, stirring, until the soup has simmered for several minutes. Season to taste with salt and pepper.
Bring a large pot of water to a boil and turn off heat. Drop in almonds. Leave for 2 minutes, then pour almonds into strainer or collander. Cover with cold water. Peel almonds by slipping each nut from its skin. Place almonds on a towel paper lined cookie sheet and dry in an oven set on its lowest temperature setting.
