If you have the premium subscription of MyFitnessPal, you can scan the barcode to find the recipe. While many of the recipes are in MFP, some you may have to enter manually and save as a recipe for future use!
To create a new recipe from the Diary:
Go into your diary and Log Food.
At the top, select My Recipes.
Select Create a Recipe then Enter Ingredients Manually or Add From Web
If you choose to use Add From the Web you'll need the URL for the recipe (example: https://www.myfitnesspal.com/)
Enter the recipe Name and number of servings**
If you choose Bulk Import, put in the list of ingredients and the system will choose the best match. You will be able to check update these later
Select Add Ingredients (type in the search field)
You will not be able to use items from your recent/frequent/my foods list
Select Next then review your recipe and Save or Save & Log It.
** If you're not sure how many servings a recipe will produce, enter a best-guess number when you first create the recipe.
After the recipe is cooked, you can evaluate the number of servings that have been produced. Then, the recipe can be edited and the correct number of servings can be entered.
