Add the seasoned flounder fillets to the pan when the oil begins to shimmer. Saute the flounder for roughly 3 to 4 minutes per side, or until the flesh becomes opaque and is firm to the touch. If you are unsure if the fish is done, use an instant-read thermometer. The flounder is thoroughly cooked if the internal temperature is 145 Fahrenheit.
In my experience, the secret is simply patience. How long to grill bratwurst depends on how you grill them. You can throw them straight on the grill which will take about 25-30 minutes or boil the brats in beer, wine or water for about 20 minutes. After boiling, then they are grilled for 4-6 minutes. Boiling them first (also called par-poaching) in beer first improves the flavor so dramatically its almost a sin just to throw them straight on the grill. Regardless, brats take a little while to cook thoroughly.
