This is an Irish dish that is traditionally served on Halloween (since cabbage is in season then), but it's good just about any time of the year!
1/2 head large cabbage
6 large potatoes, peeled and quartered
1 large shallot
1 tbsp butter
~1 cup milk
salt and pepper to taste
1-2 tbsp butter, melted (optional)
In a large saucepan, boil cabbage until tender; remove from heat and drain. Chop well, aside and keep warm.
Boil potatoes until tender. Remove from heat and drain.
Chop shallots and simmer them in just enough milk to cover, until they are soft. Add boiled potatoes, milk, and mash well. Season with salt and pepper to taste. Blend in the cabbage until well-combined. Add additional butter, if desired
