Tomato-Water Sorbet With Mint

Preparation

1. Step 1

   Remove stems from tomatoes and place in a food processor with the salt. Run for 30 seconds until well broken up, but not a purée. Add the mint. Run for 10 more seconds.

2. Step 2

   Place a cotton cloth (a thin towel, not cheesecloth) in the bottom of a bowl and pour the contents of the food processor into it. Bring the corners together to form a pouch and tie together with string. (The tomato water will already start to drip out.) Lift the towel 3 to 4 inches above this liquid and suspend over the bowl in a cool place. Allow tomato water to drip into this bowl overnight.

3. Step 3

   The next day, add the lemongrass and heat the tomato water without boiling, using a ladle to skim off any particles that rise to the surface. When the tomato water is clear, correct seasoning with Fleur de Sel and freshly ground white pepper. Refrigerate for at least 2 hours before churning in an ice-cream machine. Set up to finish in the freezer.
