Tiger Butter Fudge Tips
How do I store tiger butter fudge?
Like other fudge recipes, you can store this fudge in an airtight container at room temperature or in the fridge. Fudge at room temperature will last for about 1 to 2 weeks. In the fridge, fudge lasts a bit longer—typically up to 2 to 3 weeks.
To achieve a beautiful, clean swirl, use a sharp knife or a toothpick to cut through the melted chocolate. If you don't feel like fussing with a swirl, try out this Peanut Butter Chocolate Fudge. Looking for more tips? Check out our fudge guide!
