Hercules Candies peanut brittle is family tradition. Our peanut brittle is thin and crispy and made with flavorful Spanish peanuts - just the way our grandfather made it. Our peanut brittle is made with pure ingredients that you probably keep in your kitchen: sugar, corn syrup, peanuts, salt and baking soda. We don't use any preservatives or chemicals. The peanut brittle is "accidentally vegan". We have had a few reports of brittle getting sticky or clumpy in very hot climates and adding a cold pack may help prevent that.
