similar recipes
Is your feature request related to a problem? Please describe. The HF DB contains a lot of similar recipes, with either the same ingredients with a newer "revision" or variants of it (different side dishes). When using the search, you often find three or more of the "same" recipe, with one or two of them having a PDF attached.
Describe the solution you'd like I haven't checked how data is structured, but I guess a similarity algo could provide "recipes like this one" in various ways. This would also help to find PDFs. I'd propose to show this data on the page suggested in #45. It might also help to group search results, but I have no clever idea for this implementation.
Describe alternatives you've considered You already mentioned on reddit how it's a PITA to deal with the various free form units (and make this variant thing explicit) - having tried something similar already, I feel you :D
