FAQ
Can I use regular salted butter instead of unsalted?
Yes, but reduce the added salt by half since salted butter already contains sodium. Taste and adjust seasoning as needed.
How long does this butter keep in the freezer?
Properly wrapped compound butter keeps for up to 3 months in the freezer. Slice before freezing for easy portioning.
What if I don't have fresh rosemary?
Use 1/3 teaspoon dried rosemary instead, or substitute with fresh thyme, oregano, or basil for different flavor profiles.
