What Makes Japanese DIY Candy Kits Different

The biggest difference is how much happens in one small pack. Colors change, candy puffs up or foams, and powder turns into sushi, burgers, or spinning tops. Many kits need only water, and the trays, molds, and tools are included, so you don’t need any special equipment.

The kits also recreate everyday Japanese food, from sushi and bakery bread to festival treats and traditional sweets. Kracie shows a difficulty level for each of its kits, so you can pick one that matches your skill.
