Storage: Keep in an airtight container at room temperature for up to 1 week, or refrigerate for a firmer bite. Swaps: Use peanuts or another roasted nut, or omit nuts and add more pretzels. Add-ins like crushed candy canes or mini marshmallows can be stirred in after coating. Melting tips: If using a double boiler, keep heat low and avoid any water contact to prevent seizing.
