Champ in our A-Z - Cooking Index
Champ is an Irish dish of mashed potatoes with scallions/spring onions. It is usually made more smooth by the addition of either butter or milk, or both.
Champ was originally a peasant dish with the onions added to break the monotony of the Irish potato diet. In recent years champ has become a popular addition to trendy restaurant menus and you will often find 'smarter' versions of champ which will include ingredients such as Dijon grain mustard, parmesan or cheddar as an addition to the scallion/spring onion and mashed potato mixture.
Where cabbage or kale is added to mash potato you have the Irish dish colcannon, although this is frequently mis-described on restaurant menus as champ.
