Step 1: Using a heavy-bottom, medium-size sauce pan over high heat, bring 2 quarts of water to a boil. Add 1/2 teaspoon kosher salt and 1 cup sun-dried tomatoes to the water and boil for 6 minutes. Transfer tomatoes to a colander and drain on paper towels.
Step 2: Using a food processor or blender, pulse tomatoes until smooth (or to desired chunkiness). Slowly add 1 cup extra virgin olive oil and blend until emulsified. Makes about 2 cups.
