This one I am actually cross-posting on both blogs (not just sharing). This is not only a fantastic way to preserve tomatoes but also a way to add an intense tomato flavor to any dish (as Hank says, “Think of it as the black hole of the tomato world: It is said that a teaspoon of black hole matter would weigh millions of tons. Similarly, a mere teaspoon of ‘strattu in a soup is the equivalent of adding possibly a dozen tomatoes”) without all of the carbohydrates naturally present in tomatoes.
