Why it works: Apple and cider match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 1,042 recipes mention both. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
The recipe
34 to 36 doughnutsIngredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Warm the apple cider to about 110°F (43°C). Whisk in the yeast and 1 teaspoon of the sugar, then let it stand 5 minutes until foamy.
Whisk the egg yolks, remaining 1/4 cup sugar, apple butter and 1 teaspoon vanilla into the yeast mixture. Stir in 2 1/2 cups flour, cinnamon, nutmeg and 1/2 teaspoon salt until a shaggy dough forms.
Knead 8 to 10 minutes, adding the butter one piece at a time and more flour (up to 2 3/4 cups total) only as needed, until smooth and slightly tacky.
Coat a bowl with vegetable oil, add the dough, turn to coat, cover and let rise in a warm spot for about 1 hour until doubled.
Roll the dough on a floured surface to 1/2 inch (1.25 cm) thick and cut 3-inch (7.5 cm) rounds. Place on a floured tray, cover and let rise 30 minutes.
For the salted caramel, cook 1 cup sugar and the 1/4 cup water in a saucepan over medium heat, without stirring, until deep amber, about 8 minutes. Off the heat, carefully whisk in the warm cream, 1/4 teaspoon salt and 1 teaspoon vanilla. Cool completely.
Heat the 2 quarts vegetable oil in a deep pot to 350°F (175°C). Fry the dough rounds in batches 1 to 2 minutes per side until golden, then drain on paper towels.
Mix the 1/2 cup sugar with 1/8 teaspoon salt. While the doughnuts are still warm, roll them in the sugar mixture. Once cool, pipe the salted caramel into each doughnut through the side.
