raw shelled peanuts, skins on
Heat sugar, syrup, water and salt to a rolling boil in a heavy iron skillet. Add peanuts. Reduce heat to medium and stir constantly. Cook to hard crack stage (293° F).
Add butter and vanilla, then baking soda. Beat rapidly and pour onto a lightly greased baking sheet, spreading to 1/4-inch thickness. When cool, break into pieces. Store in an airtight container.
NOTE: You can change it up by using just 2 cups of peanuts along with 1 cup of flaked coconut.
