Many people try to avoid mayonnaise for diet reasons.
In November & December that’s impossible because it’s a crucial part of some of the most classic dishes you get for the classic. Danish Christmas Lunch.
A Rejemad without mayonnaise is a crime! And the Hønsesalat (chicken salad), the Tunsalat (Tuna Salad) or the Karrysalat (Curry Salad) that goes with the Herings wouldn’t exist without mayonnaise.
And the Fiskefilet (Breaded Fish filet) is only an excuse to eat the tasty yellow substance aka Remoulade which basically is mayonnaise LOL.
