Start by rinsing your grapes in a colander under cold water. Then, pat them dry with a clean kitchen towel. This step is key because if grapes are wet, the coating won’t stick.
Pour lemon or lime juice into a bowl, then toss your grapes inside until they’re evenly coated. The juice acts as the “glue” that makes the sugar or gelatin stick perfectly.
Now comes the fun part! Roll each grape in a shallow dish filled with your chosen coating—gelatin powder, sugar crystals, or even fruit powder. Make sure every grape is fully covered.
Place your coated grapes in a single layer on a parchment-lined baking sheet. Pop the tray into the freezer for at least 1–2 hours until they’re completely frozen.
Once frozen, transfer them to an airtight container or serve immediately. They’re crunchy, sweet, and incredibly refreshing!
