>hummus is an ingredient too
Hummus is a final product with an ingredient list and will 95% of the time be eaten as that final product just with things dipped in it and you're being a disingenuous faggot if you pretend otherwise
>arbitrary definitions
No, because I would still call a product an ingredient to a common household if it was something that was a specialty artisan product that you had no way to conceivably make at home in a reasonable manner, like many-years-aged parm or iberico ham. But hummus is fucking easy to make as a product using ingredients that are reasonable to keep in a household that focuses on base ingredients, so fuck you. That's the distinction and it's a fucking obvious one.
If you're buying hummus, you're not limiting yourself to purely ingredients in your household because it's very easy to make hummus from actual ingredients. You're choosing to purchase a pre-made product with a clear, easy-to-produce recipe that is ready to eat for convenience in your home, which is the opposite of limiting yourself purely to ingredients that you then cook with yourself.
Unless you think it's unreasonable to source the ingredients for or make hummus, in which case I pity you.
