Why Do You Put Baking Soda In Peanut Brittle?
Baking soda is added to peanut brittle to create a chemical reaction with the other ingredients, specifically the sugar syrup. The baking soda causes the mixture to foam and expand, which makes the candy more airy and brittle after it has hardened. It also helps to neutralize the acidity in the recipe, which can help create a smoother texture and prevent the sugar from crystallizing.
