Peanut Brittle

2 cups sugar
3/4 cup corn syrup
1/4 cup water
1/8 tsp. salt
2 cups raw peanuts
2 tsp. soda

Put sugar, syrup, water and salt in pan and cook until sugar melts. Add raw peanuts. Do not stir, but watch. Cook until candy reaches hard-crack stage. Remove from heat. Add soda, and stir quickly. Mix well so it will puff up. Pour on greased surface and spread thin layer. It hardens quickly. If it is cooked enough, it will not stick to the board.
