The search engine here at WordPress is a VERY good one! So if you’re looking for recipes that use a specific ingredient, just type it in the search box at the top of the sidebar at the right and only those recipes with that food as an ingredient (or mentioned in the narrative as a possible variation on a recipe) will be pulled up for you to review. It rarely makes mistakes, unless there is a typo in the keyword(which renders a “No matches found” response).
You can also type a recipe title (or close to it) in the search box that you know you saw on my site and WordPress will attempt to find that particular recipe for you. It has been pretty good on that function also, but the title must be entered pretty close to the actual title for that to work and avoid the dreaded “No matches found”.
I calculate my nutritional stats at Fitday.com, which utilizes the USDA Foods Database. Foods that are not in their database, I key into an additional personal database using the data on the Nutritional label on the food package/can/jar/bottle itself. When I list nutritional info for my recipes, as a rule, I do not bother to include the macronutrient if it is <10% RDA. Just wanted you to know in case you are comparing my macros against another tracking program and wonder why one isn’t listed. I don’t consider <10% RDA to be a significant amount of a nutrient.
