MasterCook imported the ingredients and nutrients from the USDA FoodData Central databases. Recipes call for ingredients by a variety of names. The USDA does not have every ingredient or multiple variations. However, you can easily create synonyms or add your own ingredients from within the Ingredient List in MasterCook.
In order to assist you in locating a similar ingredient, we have provided a text file of the ingredient names used in MasterCook. See the attached .txt file below. Download the file to your computer. Use it to search for an ingredient by its name to see where it is in the list.
MASTERCOOK 15 AND OLDER
The older versions of MasterCook have about 9,000+ ingredient names from a 1990's version of the USDA Standard Reference database. It is very old.
There are over 16,000 ingredient names in MasterCook 2020. They are from the USDA Standard Reference Legacy database. The USDA last updated this database in 2019. As stated on their website, they are no longer updating this database. It is final and complete.
There are over 333,000 ingredient names in MasterCook 22. It is a combination of the final USDA Standard Reference Legacy database as well as the Branded Foods database (Oct 2021 release). The USDA states they are only updating the Branded Foods database going forward. Food manufacturers provide their nutrient data to the USDA.
Additionally, MasterCook 2020 and 22 have more than 3.5 times the number of nutrients than any previous version of MasterCook, including sugar and phosphorus for those who need to watch those levels of nutrients because they have diabetes or kidney disease. It took a great deal of effort to rewrite several parts of the program to work with all of those new nutrients.
You can either link your unknown ingredients in a recipe to one in MasterCook's internal database or you can create a synonym of an existing ingredient in the Ingredient List in the program. The program's Help explains how to do these things. It has a Search tab too. Just search for link or synonym to find those instructions. Go to the Help menu in MasterCook. Select Help Contents to access the program's help. If the window doesn't appear, just restart MasterCook try again.

If you add or edit the Ingredient List, you will want to make sure you regularly backup the MC Ingredients.ing file that's inside the MC Tools folder on your computer. It contains all of your edits.
