Step 1
In a small bowl combine the yeast and warm cider; set aside until it foams up, about 5 minutes.
In the bowl of a stand mixer fitted with the hook attachment, combine the melted butter and sugar, and - using a silicone whisk - mix until well combined. Whisk in the egg, egg yolk, salt, nutmeg, cinnamon, yeast mixture, and 3 cups of flour, and beat on medium-low speed until smooth. Beat in remaining flour just until a soft ball of dough forms around the hook. Don't knead the dough yet!
