Quarter the Brussels sprouts. Peel and finely dice the shallot. Fry the bacon in a pan until crispy.
Sweat the shallots in a pan with 1 tablespoon of butter, add the Brussels sprouts and toss briefly. Then mix in the bacon cubes and add the cream. Simmer until the Brussels sprouts are cooked through, but still firm to the bite, and season to taste.
