Tomato Salt

Preheat oven to 225°F. Spread tomato paste in a thin, even layer on a baking sheet lined with a silicone baking mat. Bake 25 minutes or until paste is dry, slightly pliable in center, and brittle around the edges. Cool completely on mat; break into small pieces. Process tomato pieces into a fine powder using a spice grinder. Add sea salt flakes; pulse 3 to 4 times or until salt flakes are coarsely chopped. Store in an airtight container up to 2 months.
