I've cooked with it occasionally for other people, sure, but personally just about the only thing it adds to any meal is a worse taste, heh. Usually badly enough I'm just like, nah, I'll pass.
There's an exception or two (for whatever reason, sour cream and onion chips are fine, though I don't like the taste of sour cream or onion on their own, ha, and I can't even taste the stuff in the curry powder I've been basically mainlining for the last while), but generally it's just... bad. To my taste buds. Onion powder isn't quite
as bad, but it's still mostly just kinda' nasty.
It's honestly a bit of a conundrum; I really dislike onions, and there's someone else in my home that really dislikes
garlic, so between the two of us it's like just about everything in a store or whatever can go to varying degrees of hell
Add in there's a salt restricted diet involved, on top of a diabetic, and grocery shopping for stuff you don't make from scratch is... difficult. Basically everything has either onions or garlic, usually both, carb watching is its own mess, and basically goddamn
everything frozen or canned or whatever is just friggin'
drenched in salt.
There's a market niche for low carb/low salt easy cooked meals that isn't being filled in US grocery stores, right now.
