Help me make Apple Cider Doughnuts.
Here's a recipe for Apple Cider Doughnuts:

Ingredients:

• 2 1/2 cups apple cider, reduced down to 1/2  cup (120 ml)
• 1/4 cup butter
• 1 cup granulated sugar
• 1/2 cup light brown sugar
• 2 large eggs
• 1 tablespoon vanilla extract
• 3/4 cup sour cream
• 4 cups flour
• 1 1/2 teaspoons salt
• 2 teaspoons baking powder
• 2 teaspoons cinnamon
• 1 teaspoon nutmeg
• canola oil, for frying
• cinnamon sugar, for coating

Instructions:

1. Bring apple cider to a boil over medium-high heat. Reduce down to 1/2 cup (120 ml) (takes about 20-25 minutes). 
2. Pour into a large glass measuring cup.
3. Add butter to hot cider and stir to melt. Set aside, cool.
4. In a large bowl, whisk together eggs with white and brown sugar. Add cooled cider/butter mixture, sour cream, and vanilla extract.
5. In a large bowl or in a fine mesh strainer set over the wet ingredients, sift together flour, baking powder, salt, cinnamon, and nutmeg.
6. Using a wooden spoon, mix dry ingredients into the wet until just incorporated. 
7. Cover and chill for 1 hour.
8. On a very well-floured surface, roll out the cooled dough to about 3/4-inch (2 cm) thickness and cut into donut shapes using pastry cutters or a mason jar/cup and a bottle cap/shot glass. Chill cut donuts 10 minutes more if necessary.
9. Heat oil to 350˚F (180˚C).
10. Fry donuts, 3-4 at a time, flipping occasionally until golden on both sides.
11. Remove to a paper towel lined baking sheet to drain. Roll in cinnamon sugar while still warm.
