Hi, I’m a dietitian and wanted to clarify.. when we calculate nutritionals we don’t weigh the ingredients we use a formula to figure out caloric content based on grams of the macronutrient that is contained in the volume. Some ingredients have more than one macronutrient. For example, flour contains carbohydrates as well as protein. The best way to estimate the breakdown is to use an app or website that is reliable. But these are always estimates at best and likely inaccurate to some degree. Your calcs sound too high just based the volume and content of what’s in this recipe so maybe try punching it into app instead. Hope this helps.
