Compound butter is just flavoured butter. LegourmetTV shows you how to make garlic butter, which is a good companion to fresh bread. One clove of roasted garlic is added to half a cup of unsalted butter to make simple garlic compound butter. You can also add cinnamon and sugar to butter for toast. Alternatively, you can even add any of your favourite herbs to melt down a steak. You can also shape the butter into a log, wrap it up in baking paper and keep it in the refrigerator for storage. The frozen butter logs can be easily sliced before serving.
