Make Recipe Module Compatible with Similar Entries

First of all, thank you for this great module. It helped me a lot while creating my new recipe site.

For me currently there is one major issue with using the Recipe module though: It is not fully compatible with Similar Entries (tested with version 7.x-2.0-beta5). The module shows irrelevant results because it doesn't manage to scan the custom fields, like instructions and ingredients, which the Recipe module uses - apparently Recipe custom fields aren't typical CCK fields.

For me this is an essential "feature" because it greatly enhances the functionality of the Recipe module: Visitors view a certain recipe and they automatically receive suggestions with similar recipes. One could argue that it would be possible to use a different comparison module (like similar by terms) but unfortunately recipes are often grouped by rather broad terms like "Dessert" and a comparison by taxonomy terms would lead to broad results which wouldn't be of much use.

I realize that this might be a module specific request, however I do think that many site owners who use the Recipe module could profit from such a compatibility fix, as similar content modules are a very popular addition to content driven sites in general.

If someone could have a look at this, it would be great. I would be willing to chip in about $100 for a proper fix.
