This is one of those non-recipe recipes, terribly inexact. It's the way my mother always prepared bluefish and mackerel and other difficult (and correspondingly affordable!) fish. Everyone loves it and it can be on the table in approximately 10 minutes. —Sadie
bluefish or mackerel fillets
Mayonnaise - 1 cup or so. Homemade's best, but I also use Hellmann's doctored with mustard and lemon, have added creme fraiche, etc.
