Choose a butter that fits your tastes and budget. Unsalted butter is a great choice and gives you a blank canvas, but you'll need to add salt to round out the flavor.
Fresh garlic is essential for this irresistible spread. Fresh garlic will be firm and shouldn’t have much of its notoriously pungent smell until after you peel it.
If you can’t access fresh, garlic powder can be used as an alternative. For every garlic clove your recipe calls for, substitute a quarter teaspoon of garlic powder.
A common method of doing this is to wrap the garlic heads in foil (slice the pointy tops off first) and roast them directly on the oven rack for at least 30 minutes.
You’ll need to prepare your ingredients well. You’ll want to use softened butter, which can be achieved by leaving it at room temperature for 30-60 minutes.
You’ll want to mince your garlic into small and even pieces, which will distribute the garlic flavor throughout the butter, making the flavor much smoother.
