recipe - ingredients - subingredients

[GregO]

hello,

I have a recipe file ,that is no problem. But when certain ingredients are composed by raw materials, I have a problem. I also want the opportunity to see what resources there are in a recipe. You understand?

example:

A cold buffet (recipe) consists of mayonnaise, tomato, ... (ingredients). And mayonnaise is made up by oil, egg, salt, mustard (raw materials).

I want the ability to then see what to order for making the cold buffet. i.e. tomato, oil, egg, salt, mustard, ...

i have allready search on some forums but didn't find the solution.

Can someone help me?

You could place a portal to raw materials on a layout of recipes. However, if you want to see a list that combines ingredients AND raw materials, you may need to re-evaluate your data model.
