Peanut Brittle

Combine sugar, syrup and water in a pan. Cook slowly, stirring until sugar is dissolved. Cook to soft ball stage (test in water). Add peanuts and salt, cook to hard crack stage, stirring constantly. Add butter and baking soda. Pour onto buttered cookie sheet. Cool partially by lifting around edges with spatula. Keep spatula moving under mixture so it won't stick. Turn when firm and warm. Pull edges to make thinner. Break into pieces when cold.
