  4. In a medium saucepan, melt 3 tablespoons butter over medium-low heat.

Chef's Tip for Extra Flavor

Chef's secret: layers of flavor make a dish truly memorable! Consider what a little extra something could bring – perhaps a touch of acidity like a good vinegar or citrus zest, a hint of smokiness from paprika, a bit of umami from mushrooms or soy sauce, or a sprinkle of toasted nuts for texture. Experiment and taste as you go!
