Hot buttered rum is warmly spiced and soothing on a cold winter's day. Make-ahead butter, warm cider, and spiced rum make a cozy mug of comfort.
Mix together the butter, sugar, spices, salt, and lemon zest until well combined. Store mixture in the refrigerator until ready to use. (Butter can be wrapped tightly and frozen for several weeks.)
Add 1 Tbsp orange juice to each mug and whisk well. Sit back, sip, and enjoy!
