Preheat oven to 350 degrees and grease 6 muffin tins.
In a large bowl, combine milk and apple cider vinegar and let sit for 5 minutes. Stir in melted butter.
Mix all dry ingredients and add to wet. Stir well, then add mixins.
Divide batter evenly among 6 muffin tins. Bake for 20-25 minutes, until a toothpick inserted in the centre comes out clean. Let sit for 10 minutes before transferring to cooling rack.
Make the butter: In a food processor (or a small bowl, using some elbow grease), add butter, minced sage, and honey, and pulse until butter is light and fluffy, scraping down the sides as needed.
Enjoy warm stuffins with a generous smear of honey sage butter.
