Slice off the root ends on the pearl onions and drop into boiling water. Drain and rinse with cold water. Pinch the stem end, and the peeled pearl onion will pop out. Set them aside.
In a large skillet over medium-low heat, melt butter. Whisk in flour and continue whisking until the mixture is light golden brown. Slowly whisk in milk and continue whisking until the mixture thickens slightly.
