I am currently finding that out, too. 🙃
So far, I’ve had them in a vegetable curry and in a sort-of-East-Asian style dish (rice, chickpeas, teriyaki, sriracha, peanut sauce) and I threw them onto a toast where I had a tomato-hummus spread on there.
I feel like that generally works quite well, if your base food is already quite rich in either veggies or spices, then you can just throw chives into the mix without it poking out too much. Lots of those dishes might use leek anyways, and chives aren’t too different from that.
The search term persistence is nice, when you want to change what you searched for, e.g. add another word to narrow it down more. It’s been the behavior on mobile for a while, and I was skeptical at first, too, but you just really don’t need to see the URL of your search engine. Well, unless you’re trying to add it to the browser, but at that point, the search term persistence won’t yet happen.
