This is one of those things that I make en masse and keep in the fridge for the holiday season. It's great on everything from French toast to roasted chicken. Use it to garnish a thick, char-grilled steak. Crown a steaming bowl of creamy mashed potatoes with a few slices and some minced chives.
You know how when you go to a fancy steakhouse and your steak comes with a sumptuous hunk of cold, creamy butter on it? And it's just starting to melt and mingle with the meat's perfectly charred crust to make a mouthwatering, on-the-spot sauce? Compound butter is like that, but better.
