In addition to that, you can find recipes by Region or by Special Diets, and you can even choose recipes based on the current season you're in!
All recipes can be found in at least one category in the 'Cook by Category' menu. After organizing them into categories I realized it looked pretty empty so I went ahead and added all in-game recipes to it as well.
I made this cookbook object so that there would be an easy way to find all my custom recipes.
