How to Melt Butter.
On the Stove: Place butter in a small pan and heat over low. Stir until butter is melted.
In the Microwave. Cut butter into tablespoon-size pieces. Place in a microwave-safe bowl. Heat on low for 15 seconds. Remove the butter from the microwave. Stir. Doing this prevents the butter from splattering. Repeat until melted.
