What changes the calories
- Most recipes use cornstarch by the spoonful rather than the cup, so the calories it adds to a dish are usually small compared with the other ingredients.
- When cornstarch thickens a sauce, soup or gravy, its calories are spread across the whole pot, so your share depends on how much of the dish you eat.
- Cornstarch used as a coating for fried foods adds its own calories plus the calories of the oil the coating absorbs during frying.
- Scooped measurements vary because cornstarch packs down easily, so a heaped or packed spoonful can weigh noticeably more than a level one.
Tips for logging it accurately
- Weigh cornstarch on a kitchen scale instead of using measuring spoons, since its weight per spoonful varies with how tightly it is packed.
- For thickened sauces or soups, log the cornstarch as part of the whole recipe and then log your portion of the finished dish.
- In BerryFit, save recipes that use cornstarch so its calories are counted automatically each time you log that dish.
