Tips & Tricks (5)

Color Blocking Technique 🎨
When creating jello cubes, use separate shallow pans for each color to ensure clean, distinct color blocks that won't bleed into each other.
Gelatin Dissolution Pro Tip 🥄
Always bloom gelatin in cold water first and let it sit for 5 minutes before heating to prevent lumps and ensure smooth, even setting.
Cutting Cube Perfection ✂️
Use a hot, clean knife and wipe between cuts to create precise, uniform jello cubes that will create a beautiful mosaic pattern.
Condensed Milk Balance 🥛
Use room temperature sweetened condensed milk to help it blend more smoothly with the gelatin mixture and prevent unexpected clumping.
Chill Layer Strategy 🧊
Allow each layer to partially set in the refrigerator for about 20-30 minutes before adding the next layer to prevent color bleeding and maintain crisp edges.
