Have you considered the ability to filter out recipes that don't contain a particular ingredient?

Obvious use cases are food allergies and dislikes in general.

My specific use case is that I searched `guacamole` and got 2k that contained `salt` but only 1.8k that contained `avocados`. I want to see the recipes that don't use avocados.

EDIT: It appears that `avocados` and `avocado` are separate ingredients, as are `tomatoes` and `tomato`. I know pluralization rules are hard, particularly in English, but any chance of a cleanup pass for the... low hanging fruit?

As an avocado fan I have trouble grappling with the concept of guac made without them. Isn't that sorta like orange juice made from things that are not oranges? Feels almost oxymoronic. Good suggestion though.

When I say "I want to see the recipes without avocados" it's kind of like when you witness a car crash. You're not looking because you want to see someone crash, you're looking because it's horrifying. Same with avocado-less guacamole. The concept is horrifying so I need to know.

And yes, I would absolutely love to see the recipes for orange juice that don't include any oranges for the same reason.

Either way though, I think it's just because `avocado` and `avocados` are counted as different ingredients.

Orange flavouring, orange coloring, citric acid, sugar, and water.

Or mashed edamame apparently

Ah interesting use case with food allergies and exclusions. Added this to my todo list.

I see what you did there with low hanging fruit! I'll take a pass at de-duping plurals in ingredients. Good catch!

Not just allergies. I was just looking for biscotti recipes and there's basically two styles of biscotti: made with butter (the soft chewy kind) and made without (the crispy you'd better have a drink to dip it in kind). It's impossible to search for the latter without excluding butter.

It appears that you can do -<word_to_be_filtered>

>"My specific use case is that I searched `guacamole`"

Guacamole was my first search as well. Must be something in the air ...

Easy to make, few ingredients, and easy to imagine people screwing it up by putting all sorts of nonsense in it.

In other words, a great test of a recipe search.

Back when I worked on eHow used to find the most ridiculous pages to test with. There was one that was something like “how to make ice water”. Apparently enough people searched for it for it to be worth writing up.

Another good recipe I see butchered is quesadillas. Something with Mexican food and people messing up.
