I have a good expereince with Google search and Excel spread sheet - which is what is required here. I have done some projects which are similar to yours.
First of all, you take a blank excel spread sheet, and make 5 columns, 1 for recipy, 3 for,minerals and 1 for total. Each row will have one recipy.. At the end, you sum the minerals to give you the total for each recipy. For each recipy, you search by Google the amounts of 3 minerals in the said recipy.
