Clarify the butter. Place it in a small saucepan over medium-low heat and cook until it just begins to bubble. Remove from heat and skim off any solids. Slowly pour butter into a small bowl, leaving the heavy solids in the bottom. Let come to room temperature. Place the lettuce in a large bowl, sprinkle with the butter and the lemon juice. Adjust to your liking. I probably wouldn’t use all the butter. Season with salt and pepper to taste.
