How to organize this: traders have fruits and recipes too I'm building a site in D7 for a little community garden mall with 30 traders/shops. There is a trader which sells fruits, another one sells cakes, another one sells dairy products, and so on.

And I have a page with lots of recipes. The recipes should link to the traders. So for Spaghetti Aglio e Olio: The spaghetti you buy at the wheet farmer, the garlic at the vegetable farmer and a white wine at the liquor shop.

I have a content type trader. And a content type recipe.

How do I organize the products? 
We even think about selling some of the products online one day. So that a site visitor could order a box of vegetables of a trader.

Thanks, Joerg
I would look into using the references module, you can reference one content type from another, for example on a ingredient page such as white wine, you could reference Spaghetti Aglio as a "you can make this from this ingredient".

Then on a traders content type you can refer to the ingredients etc
