Fancy making a Big Mac at home? topsecretrecipes.com has loads and loads of recipes for well known (mostly American) fast food items, sauces, and other brand name foods.

I haven’t tried to make anything off here, so I can’t judge how good it is, but they must be quite popular given their book range (available in the UK here).

Only some of the recipes on the site are free, but that does include Big Mac Sauce!
