I noticed this post last night but didn't really know what to say so I left it for someone else. However, I don't want you to feel ignored.
What do you mean by recipe? Do you want a pattern or general guidelines on how to construct your garment? I think of a recipe as something which will guide you but doesn't tell you exactly what to do, as in how to make socks without a pattern. Which one did you look at on here but don't like? There are tons of patterns out there so something to narrow it down would help. Have you looked at ravelry or knittingatplay.com?
I should never overestimate my basic arithmetic skills.
