Warm milk in a microwave-safe container. In a saucepan, melt butter over medium heat. Add flour and stir continuously until raw aroma dissipates, about 1–2 minutes. Gradually add warm milk, whisking to prevent lumps. Continue cooking until sauce thickens to coat the back of a spoon. Season with salt, nutmeg, and black pepper. Remove from heat and set aside.
