- The jelly didn't set.
- Either there was too little gelatin, you boiled the gelatin (which destroys its binding ability), or it contained kiwi/pineapple.
- What's wrong with kiwi and pineapple?
- These fruits contain an enzyme (bromelain/actinidin) that breaks down gelatin. You can only use them in jelly if cooked (canned)!
Fresh Fruit Gelatin Cake
The essence of a fruit jelly is the colloidal state: gelatin (a protein) dissolved in water creates a mesh structure while cooling, trapping the liquid. This turns liquid fruit juice into a jiggly, solid dessert. For a clear, transparent result, it is important not to boil the gelatin and to patiently wait for it to set.
Ingredients
Equipment Needed
- Small saucepan
- Molds or glasses
- Whisk
Instructions
Wash the fruits and cut larger ones into bite-sized pieces. Arrange them at the bottom of molds or glasses.
Bring half of the water (1 cup) to a boil with the sugar, vanilla, and lemon juice until the sugar is completely dissolved.
Mix the gelatin powder into the remaining cold water and let it sit for 5 minutes (bloom).
Remove the sugar syrup from the heat, wait 1 minute (it shouldn't be boiling!), then stir in the bloomed gelatin until completely dissolved.
Let the liquid cool to lukewarm, then pour over the fruits. Refrigerate for at least 4 hours.
