Granulated Sugar (Best Option)
1 tablespoon per 1 tablespoon powdered sugarGranulated sugar is chemically similar to powdered sugar minus the cornstarch, making it an effective sweetener in tomato sauce. When heated, it dissolves into the sauce, balancing acidity and enhancing natural tomato flavors.
To ensure it dissolves completely, add granulated sugar early in the cooking process and stir well. Avoid adding it at the end to prevent graininess.
Compared to powdered sugar, granulated sugar may require slightly more time to fully dissolve but does not affect the sauce's texture or flavor negatively, making it a reliable substitute.
