How to calculate more accurately
For a spoonful or cube, use the package weight or weigh it. Level and heaped spoons hold different amounts.
The 5 g and 10 g servings are calculation shortcuts, not universal teaspoon or tablespoon capacities.
USDA lists 387 kcal per 100 g for this record. Labels may show around 400 kcal due to calculation and rounding methods; use your brand label when available.
