How to Make Any Compound Butter
The better quality the butter, the better the overall results. Chef Ashley Fahr from Cookdrop Kitchen recommends using European-style butter that has a higher fat content such as Plugra or Kerrygold. Combine unsalted, room temperature butter with your choice of aromatics, spices, or fresh herbs. Then, add salt, pepper, and preferably some type of acid such as lemon juice to balance out the flavors. Mix the flavors well by hand or throw everything into a food processor to thoroughly combine. Roll the butter mixture tightly in parchment paper to form a log and tightly sealing the ends before storing in the fridge to firm for at least an hour or up to one week. Compound butter can also be stored in the freezer for up to one month.

Get The Proportions Right
While there are no set proportions to use for compound butter, the ideal tends to be about one stick unsalted butter (8 tablespoons), ½ teaspoon salt, ½ teaspoon freshly cracked pepper, and 2 tablespoons fresh herbs. From there, add the other ingredients such as lemon juice or paste mixes to taste.

The beauty of miso is that it provides most of the flavor, which minimizes the need for other seasonings. Martha Stewart offers an easy version of this two-ingredient recipe.
Slice & Serve
To serve compound butter with fish, bring the log to room temperature and slice off thin coins. The width of the slices will depend on the diameter of the compound butter log: You want approximately 1 tablespoon per slice or serving, so slice accordingly. Top each fish fillet (or hot vegetables) with the coin of butter and serve immediately.
The heat of the fish will melt the butter, creating an instant sauce of sorts and plenty of flavor.
