Peanut Brittle

Take two cupfuls of light brown sugar, one cup of corn syrup, one-half cupful of water, one tablespoonful of butter and cook to the crack stage, then add a teaspoonful of vanilla, and two cupfuls of peanuts that have been slightly roasted, and stir until it begins to turn brown. Be careful not to let it burn, or become more than a golden brown in color. Add one tablespoonful (level) of soda, stirring it quickly, then pour over a greased platter or marble slab. As soon as it is thin enough to handle, loosen from the platter or slab with a knife, turn over and stretch out very thin. Break up into any desired shape when cold.
