In a previous job I worked for a site doing natural language parsing on recipes.

We noticed one of our partner websites had an unusual number of unique ingredients. It turned out every ingredient was a link to another recipe to make that ingredient, along the lines of your idea.

However for some reason (presumably SEO) they took this to the extreme and everything was a recipe. Including apples.

The recipe for “apple” is

1. Take 1 Apple

2. Eat and enjoy

But since Apple is a prerequisite for this recipe, infinite looping is a risk in the kitchen now
