3/4 cup Water (divided into 1/2 cup and 1/4 cup)
24 oz Berries of your choice (~5 cups)
1 1/2 cup Allulose (to taste)
5 tsp Unflavored gelatin powder
Combine 1/2 cup water and blackberries in a medium saucepan. Bring to a boil, stirring and mashing as berries soften.
Reduce heat to medium-low. Simmer for 5 minutes.
Line a mesh sieve with a jelly bag or nut milk bag and place over a bowl. Pour the berry mixture over the sieve. Press with a spoon or spatula to push the juice into the bowl. You should get about 2 cups of juice (add water to reach this amount if you don’t get enough).
Meanwhile, pour the remaining 1/4 cup water into a small bowl. Sprinkle the gelatin powder into the bowl. Stir together, then set aside to bloom for at least 5 minutes.
Pour juice into a small stainless saucepan over medium heat. Add Besti and stir to dissolve. Taste and adjust sweetener to taste if needed – keep in mind it will seem less sweet after it sets, so make the liquid a bit sweeter than you want.
Reduce heat to low. Stir in the bloomed gelatin and heat, stirring, for about 2 minutes, until gelatin dissolves.
Pour the liquid into a jar. Refrigerate for at least 5-6 hours, or overnight, until set. Stir with a butter knife or spreader.
