Compound butter is basically butter with added ingredients for extra flavor. The varieties are endless. Today I made an herb butter. The original recipe calls for 2 tablespoons of chives and one tablespoon of sage, plus rosemary and thyme. I didn't have chives or sage so I used rosemary, thyme and garlic.
1 lb. butter (4 sticks) softened
3 -4 tablespoons of extra virgin olive oil
1 tablespoon of thyme, chopped
1 tablespoon of rosemary, chopped
1 glove garlic, minced
Equipment: Stand up mixer and food processor.
1. Cut the butter into small cubes and place in the working bowl of the stand up mixer.
2. Place oil and herbs in the food processor and blend until herbs have colored the oil, about 1-2 minutes.
3. Using the whisk attachment on your stand up mixer, using a medium speed, whip the butter until soft and light, about 5-7 minutes.
4. Add herb oil to butter and beat another 2 minutes.
It will look like this:
