Not only that, but many ingredients of recipes are recipes themselves - in a moussaka, for example, bechamel sauce is a dish all on its own, as well as an ingredient. Then Solanum esculentum is known as aubergine, egg-plant, brinjal, melongene, or guinea squash and, is a species of nightshade - so a warning that 10% of people have an allergy to it might be useful. A good ontology would also note that it's a good source of potassium. It might also be wise to have a warning that this particular ingredient contains the largest concentration of nicotine than any other edible plant. Quite a few different properties, and that's before you consider whether the mode of preparation is a relationship or an ingredient. I wonder how an ingredient ontology would deal with a copper bowl that is, apparently, essential if you want the best whipped egg-white.
