If you make tomato sauce, why not also make a tomato powder from the tomato skins? I am amazed at the aromatic essence of tomato that is captured in the dehydrated skins. Tomato powder adds a bit of zero-waste comfort. When I use it for flavoring soups, salads, sandwich fillings or pizza dough, I recall summer in the depths of winter, and I feel more connected to the cycle of life.

Ingredients:

Tomato skins (see tomato sauce recipe, opposite)

Paprika, chili powder or sea salt (optional)

Method:

  1. Lay the tomato skins on dehydrator racks or a drying rack for baked goods so that they are flat and not overlapping; a few millimeters of space between them promotes air circulation. If using a dehydrator, place the skins in the machine and turn on the vegetable setting. Check regularly but allow 4-5 hours.
  2. Alternatively use the oven on its lowest setting. Put a single layer of the tomato skins on a wire cooling rack on top of a baking sheet and dehydrate for 5-10 hours — overnight is a good idea. Remove the skins when they are completely dry and flaky. Tip into a coffee grinder and grind the skins until they are as fine as any other dried spice on your rack. Add a pinch of paprika, chili and/or sea salt for variation. Store in an airtight jar.
