Google did something similar to me last week. I was looking up spanakopita, suddenly every recipe I clicked on had egg... Which it just... Spanky pita contains no egg. I asked the AI results and it blamed Americanized versions... But I'm pretty sure all those recipe sharing sites all copy each other and it just looks like "everyone" is doing it.
Side note, I didn't need a recipe, I was checking for tidier ways to deal with thawed frozen spinach
