Instructions

  1. Step 1: Cut 2 medium eggplants into 1/2-inch cubes and 4 medium tomatoes into 1/4-inch dice. Place in a large bowl, add 4 minced garlic cloves and 2 tbsp salt, mixing well to coat. Let sit for 1 hour, stirring occasionally to release juices.
  2. Step 2: After 1 hour, transfer the mixture to a clean jar, pressing down to submerge vegetables in their own liquid. Cover with a lid but leave slightly ajar for fermentation. Let sit at room temperature for 48 hours.
  3. Step 3: After fermentation, drain excess liquid and transfer to a bowl. Add 1 tsp dried mint and 3 tbsp olive oil, mixing thoroughly. Store in an airtight container in the refrigerator for up to 2 weeks.
