About
Champ is mashed potato beaten with scalded spring onion (or chives) and a lot of butter and milk. You make a well in the mash and put more butter in it. This version adds a spoon of mustard because the site already named it that way — it is a house extra, not a museum rule. Colcannon is the cabbage cousin. Boil floury potatoes until they give, then mash them with hot milk and more butter than a diet article would like. Scald spring onions or chives in the milk so they soften and perfume the lot. Beat until the mash is fluffy, not glue. A spoon of mustard — Dijon or a grainy one — is this site's house extra, sharp against the dairy. Make a well in each serving and put a knob of butter in it so it melts into a yellow pool; that well is method, not garnish. Salt as if the potatoes were bland, because they are until you do. Serve at once; mash sits and goes heavy. Leftovers fry into cakes the next day. Do not put this through a blender. Lumps are less of a crime than wallpaper paste.

History & culture
Ulster and wider Irish home food. A main with nothing but a spoon, or a side to ham. Champ belongs to Ulster and to wider Irish home tables as a main with a spoon or as a side to ham, fish, or nothing but more butter. It is not colcannon; that cousin takes cabbage or kale. Pubs sometimes plate a quenelle of champ beside a stew and charge for the theatre. At home it is Tuesday food. Mustard in the mash is not a museum rule and should be named as a house kick so nobody thinks they have been cheated of a 'true' champ. Spring onion versus chive is a garden question. Eat it in a deep bowl. A fried egg on top is a complete supper. It is peasant calorie logic that still tastes like a treat when the butter is honest.
Potato mash with alliums is older than the branded pub. Mustard is a later kick. Named champ is a regional title on that habit. Mustard as a later kick tracks shop mustard becoming ordinary, not a Gaelic antiquity. Famine history sits behind every Irish potato plate and should not be turned into menu poetry. What you are cooking is a surviving mash, not a replica of a particular century. Industrial butter and supermarket spring onions are the modern pantry. The well of butter is a serving custom that cooks still bother with because it looks like plenty. That is the useful past: potatoes, onions, fat, and a name. Once the potato was daily food, mashing it with dairy and a green onion was the obvious supper. Shop mustard arrived later as a cheap sharpener, not as a Gaelic antiquity. Famine history sits behind Irish potato plates and should stay out of cute menu copy. The well of melted fat is a serving custom that still reads as plenty.
