The Recipe Calculator makes it easy to find out how many calories are in your favorite homemade foods.
The concept is simple: just add up the calories in each of the ingredients, and divide by the number of servings that the recipe produces. The Recipe Calculator handles all the math and unit conversions.
Let’s run through a simple recipe: home made peanut butter cookies. On the Recipe Calculator page, we’ll enter in the name of the recipe and how many servings it produces (in this case, the recipe made 41 cookies).
Now it’s time to add some ingredients. We tap “Add Ingredient.” The first ingredient is 2 cups of peanut butter. On the nutrition label, it says that 2 tablespoons of peanut butter contains 190 calories, so we enter that into the top part of the page. On the bottom part of the page, we enter the 2 cups listed in the recipe.
We tap Add to add the ingredient to the recipe.
Note: If the Add button is disabled, it means that either one of the fields is blank or that you’re trying to convert units that are incompatible (for example, trying to convert cups, a unit of measure, into pounds, a unit of weight).
Now, we repeat the process for each ingredient in the recipe.
When we’re done, we tap the Done button to add one serving of this recipe to the Today page, where the name and number of calories will be remembered in the Food History for future reference.
If we want to start a new recipe, we tap the trash can to clear the old recipe from the calculator.
