Traditional Belgian-Flemish root vegetable mash: winter carrots, sweet onions, and floury potatoes simmered together and mashed with sweet farmhouse butter and nutmeg.
In a large soup pot, place the potatoes at the bottom, then carrots, then chopped onions. Cover with salted water.
Cover and simmer over medium heat for 25 minutes until all vegetables are completely fork-tender.
Drain off water thoroughly. Add the butter and warm milk, mashing with a potato masher into a rustic textured mash.
Season with freshly ground nutmeg, salt, and pepper, serving with a hollow in the centre for rich vegetable gravy.
