Ingredients:
Put
the bread in a bowl and add water to cover. Let soak for 5 minutes until
softened.
Meanwhile,
place the almonds and garlic in a blender container (or, if using a
hand-held blender, into a mixing bowl) and pulse until almonds are finely
ground.
Squeeze
out the water from the bread. Add to the food processor. Blend to a smooth
paste.
With
the motor running, add the olive oil in a slow stream, then the vinegar
and salt.
Thin
the ingredients with 1/2 cup of water to the desired consistency.
Place
the blended contents in a tureen, wooden bowl or pitcher and add about 2
cups of water. Taste for seasoning, add more salt and/or vinegar if
necessary. The soup should be fairly tangy.
Chill
until serving time. Stir before serving into bowls. Garnish with grapes.
