Instructions
Wash Blueberries
Break the skin of the blueberry by blanching, poking, freezing, or slicing. See notes for more info.
Place on dehydrator trays lined with silicone mesh or parchment paper.
Dry at 135°F / 57°C for 12-48 hours, depending on how much you have broken them down.
Test for dryness by cooling samples and getting a 'raisin' consistency for whole, or dry pieces.
Condition if you are storing for long-term. Shake in a jar once a day to check for clumping or sticking to the jar. If you have either, throw them back into the dehydrator to dry more.
Store in an airtight container for about a year.
Powder blueberries
Put fully dried blueberries into a coffee grinder or blender.
Pulse often to break up pieces and then a quick blend to make into powder. Do not over blend as it can cause clumping.
Place powder back into dehydrator in coffee filters or into a warmed but turned off oven on parchment paper baking sheets to dry out more.
Store in an airtight container with moisture absorbers.
Notes
Breaking the skin of blueberries
Cut or poke with a knife tip or other skewer. Using something like a onion slicer (like a metal hair pick) makes the job go much more quickly. - or -
Blanch in boiling water for 30-45 seconds -or-
Freeze for 1-2 days and then press on trays if the skin isn't breaking as they dry -or-
Process in a food processor or blender until in bits or puree for fruit leather if your intention is to go straight to powder.
