When you are assembling a meal you like to know what goes with what. Each recipe in Mangia! can include a list of other, Compatible Recipes that might fit with it in a meal. This linkage does not necessarily run two ways. Recipe A can suggest Recipes B, C, and D without either B, C, or D suggesting A.
You can note that recipes are compatible in two ways. When you are editing a recipe, you can go into its Compatible Recipes part and paste the title of the other recipe there (presumably having copied it from another recipe list). The pasted recipe will then appear in the Compatibles list to the recipe you are editing, indicating compatibility.
The other choice is somewhat easier. In any recipe window, any time more than one recipe is selected you can go to the Recipes Menu and choose Link Recipes. That will link each of the selected recipes to the others’ Compatibles lists.
If you try a couple of Compatible recipes together and decide you'd rather starve than eat them together again, you can open the recipes' Compatibles lists and delete recipes to indicate that you don't think they're compatible. This doesn't happen very often, so there is no "Unmark Compatible" command on a menu.
