Frying for two days is the technic for achieving that greasy authentic flavor. I didn't like then at all.
Fried Onion didn't taste much different than the other flavors. Although, I ate them on a day after a run when I eat light, and a stop in the store on the way home. So I had the munchies when I peeled the top back.
I thought they were awful. Lol I honestly wish it was a plain Hawaiian flavor
