Equipment

  • Baking trays
  • Silicone baking sheets or parchment paper
  • High speed blender with milling canister, spice grinder, or food processor
  • Oven, with the ability to set as low as 170℃ or lower, convection optional
  • or Dehydrator, optional

Ingredients

  • fresh organic tomatoes amount variable, washed and dried, stems and blemishes removed

Instructions

  • Prepare your baking trays by lining them with parchment paper or silicone baking sheets.
  • If using your oven, set to 170°F (convection optional) or as low as 110°F.
  • Wash and dry your tomatoes, cutting out any blemishes or especially woody stems.
  • Slice tomatoes as thinly and evenly as possible while keeping slices intact.
  • Spread your slices out individually on your prepared baking trays, making sure slices do not touch to allow for better airflow.
  • Put trays into oven and check every few hours, allowing humid air to escape and checking for doneness. The amount of time needed to fully dehydrate the tomatoes is highly variable, and will depend on various factors such as how juicy your tomatoes are, how efficient your oven is, and if you have convection settings or not, etc.
  • Tomato slices are done when fully dehydrated - they should feel crispy and brittle, not chewy or flexible, and should crumble easily when crushed.
  • Put all tomato slices into a high speed blender milling canister, mill on high speed until as finely ground as possible - using the tamper to help the powder blend thoroughly if needed.
  • If using a spice grinder, crumbled the slices up first to better fit into the grinder, and blend into a fine powder in batches.
  • If using a food processor, blend until as fine as possible.
  • If using a dehydrator, follow the instructions included with your particular unit for drying damp vegetables or fruits.
  • Once ground, store your powder in an airtight glass container; you can add a food safe desiccant packet to help keep your powder dry and less clumpy (optional).
