Accidentally bought a bag is poached peanuts instead of roasted. Can I roast them despite the fact that they are already cooked (and not raw)? If so, are there any extra steps I should take in doing so?
You can, just like you would for raw peanuts. However the boiled/poached peanuts have a bitter taste that is not removed by roasting and is generally unpleasant to eat as a snack. I would use these peanuts to make peanut sauces such as satay sauce, and possibly in other dishes where the peanuts are not the dominant flavor.
2Some boiled peanuts taste less bitter than others, which I think is due to peanut variety.– EricaApr 7, 2019 at 12:01
