The Secret to Perfectly Cooked Fish: Mayonnaise
Grilled fish is a great dish at any time, but some effort must be made to keep it from overcooking or burning. Coating the fish with a little mayonnaise makes it easy to cook exactly what you want.
If the fish sticks to the wire rack, it will fall apart and spoil. Kelly Dunn of The Kitchn recommends an easy way to avoid this:
An important step to prevent the fish – fillet or whole – from sticking to the grill is to make sure it is covered in fat. While you can use vegetable oil such as canola or olive oil, there is another staple in the kitchen that I love to use: mayonnaise . Cover both sides, then season the fish before grilling.
There are a couple of other ways to keep fish from sticking – using a wooden board or even sliced lemons in bed – but mayonnaise sticks to fish better than other fats and also keeps it tender and juicy. If you don’t like mayonnaise, there is nothing to worry about. The taste and texture of the mayonnaise is not noticeable after grilling. So if you like to grill fish, you might want to buy some mayonnaise for just that.
