I've tried on many occasions to cook with peanuts into curries just by roasting them slightly and allowing them to simmer with the rest of the dish, and no matter how long I wait, the peanuts themselves always taste flat and the rest of the flavor just disappears.
Is there a conventional way to pull this off? The peanuts I'm using are stale which is part of it I'm sure, but when I eat them raw they still taste like peanuts.
