While the provided text snippet doesn't give complete instructions, it hints at the process involving drying tomatoes. Here's a general guide on how to make tomato powder at home:
Steps to Make Tomato Powder
-
Select Tomatoes: Choose ripe, firm tomatoes. Roma or other meaty varieties are ideal because they have less water content.
-
Wash and Prepare Tomatoes: Thoroughly wash the tomatoes and remove any blemishes or stems. You can blanch them briefly in boiling water to loosen the skins and peel them for a smoother powder, or leave the skins on for added nutrients and fiber.
-
Slice or Dice Tomatoes: Cut the tomatoes into small, even pieces. The smaller the pieces, the faster they will dry.
-
Dry the Tomatoes: There are several ways to dry the tomatoes:
-
Sun Drying: Spread the tomato pieces on a clean cloth or screen (as mentioned in the provided snippet, using a cloth to prevent dust is a good idea). Cover with another cloth or netting to protect from insects. This is a very long process (several days) and only works in very hot, dry climates.
-
Oven Drying: Spread the tomato pieces on a baking sheet lined with parchment paper. Dry in a preheated oven at the lowest temperature possible (ideally 170-200°F or 75-93°C) for 6-12 hours, or until completely dry and leathery. Flip the tomatoes occasionally to ensure even drying. Leave the oven door slightly ajar to allow moisture to escape.
-
Dehydrator: A food dehydrator is the most efficient method. Spread the tomato pieces on the dehydrator trays, leaving space between them. Dry according to the manufacturer's instructions, usually at around 135°F (57°C) for 8-12 hours, or until completely dry and brittle.
-
-
Check for Dryness: The tomatoes should be completely dry and brittle, with no moisture remaining. If they are still pliable, they need to dry longer.
-
Grind into Powder: Once the tomatoes are completely dry, let them cool completely. Use a food processor, blender, or spice grinder to grind the dried tomatoes into a fine powder. Work in small batches for the best results.
-
Sift (Optional): If desired, sift the powder through a fine-mesh sieve to remove any larger pieces. Regrind any larger pieces that remain.
-
Store: Store the tomato powder in an airtight container in a cool, dark, and dry place. Properly stored, it should last for several months.
