Baklava. I love it. When my aunts make it it's always amazing. But holy crap if it isn't the most tedious, fiddly, obnoxious stuff to make. And that's if you're not also making your own phyllo dough... all like six miles of it that goes in a batch one vapor thin layer at a time.
Homemade ice cream is worth it if you have the equipment for it, by which I mostly mean the actual churning machine. All the custard and stuff is a lot fiddlier if you don't have a stand mixer or a family member to mix for you, but it's still doable.
What's a food you love, that isn't worth making from scratch?
For me, crepes ain’t worth the stress to make fresh. Just buy a little pack from store and focus on filling is my go to.
