Add the ¼ teaspoon of salt and mix until just combined. Taste, add more salt if you prefer.
1/8 teaspoon kosher salt
Add the roasted garlic, mashing it with your fork. Taste the butter, and increase any of the ingredients to match your desired level of flavor. Remember that the flavors will intensify as the butter rests in the fridge.
2 tablespoons fresh roasted garlic
You can keep it in a small airtight container or roll it into a log using parchment or wax paper.
To roll it into a log, place it on a piece of parchment paper and roll it into a log shape. Twist the ends like a candy wrapper. Ideally, you will let it sit in the fridge for at least 12 hours to allow flavors to blend, but you can also use it right away.
Use the butter on a wide variety of dishes! It works great on fresh bread or mashed potatoes and is a fantastic butter for steaks.
Notes
You can use salted butter; just make sure to adjust the amount of salt in the recipe.
Mix in fresh parsley, thyme, or rosemary to make herby butter.
While fresh roasted garlic is best, those pre-minced jars will work if it is all you've got.
If you leave the butter at room temperature for an hour, it will mix much better. Otherwise, you'll probably need a food processor or mixer to make the butter.
