Why is my fantasy fudge crumbly?
Similarly, you may ask, why is my fudge crumbly? A lot of big crystals means you get dry, crumbly, grainy fudge. By letting the fudge cool undisturbed, you avoid creating seed crystals. When the fudge has cooled to 110°F, you want to start the crystallization process. You stir and stir until the fudge becomes thick.
