Method
- Step 1: Prepare the pan. Lightly grease an 8x8-inch pan or silicone mold with a small amount of oil, then wipe away the excess with a paper towel.
- Step 2: Bloom the gelatin. Pour 1/2 cup of the cold grapefruit juice into a small bowl. Sprinkle the gelatin powder evenly across the top and let it sit for 5 minutes, until it turns thick and spongy.
- Step 3: Warm the rest of the juice. Pour the remaining 1.5 cups of grapefruit juice and the lemon juice into a small saucepan. Warm gently over low heat until steaming, but do not let it boil.
- Step 4: Combine. Remove the pan from heat, stir in the honey until dissolved, then add the bloomed gelatin. Whisk until completely smooth with no lumps.
- Step 5: Pour and chill, or drink warm. Pour the mixture into the prepared pan and refrigerate about 4 hours until firm — or skip the pan entirely and drink the mixture warm right away.
- Step 6: Cut and serve. Once firm, run a knife around the edges of the pan, then cut into small cubes. Serve chilled.
Notes
Always bloom the gelatin in cold grapefruit juice first — adding it directly to hot liquid causes clumping. Don't let the juice boil, as this can weaken the gelatin's ability to set. Use unflavored gelatin powder, not collagen peptides, since collagen won't set into firm cubes. The flavor improves if you let it rest overnight in the fridge before eating — the citrus tang mellows out. Store leftovers in an airtight container for up to 5-7 days; don't freeze, as it turns watery and grainy after thawing.
