Many recipes that use juice have leftover fruit/vegetable “byproducts.” You could throw the byproduct to the birds, or compost it, but we prefer to use every part of our produce. The easiest product to make using the discarded blackberry waste from making blackberry syrup is to dehydrate the blackberry byproduct and then turn it into blackberry powder.
The first step is to dehydrate the blackberry pulp until it is very dry. (It should crumble easily.)
Blend, chop, or grind your dried blackberries in your blender or food processor for 1 to 2 minutes. It is always amazing to me how a full food processor will yield just a cup or so of powder. Chopping it up greatly reduces the space it fills.
Place the powder in an airtight container and store it in a cool, dry place. I like to use a mason jar for this.
To use the powder, add it to any recipe that you would normally use blackberries in. My favorite way to use it is in a fruit smoothy.
