**Can you make these with whole wheat flour? We don't advise it; best to get your daily fiber elsewhere.
**Can you freeze these? Yes.Freeze the batter as directed above; when churros are solid and have lost their stickiness,wrap them gently in plastic,and freeze for several weeks.Cooked,cooled churros can be wrapped airtight and frozen for up to about a month;thaw,uncovered,at room temperature;then reheat for about 10 minutes in a 350°F oven.
**Can you make these without a pastry bag? Difficult.Not suggested. kingarthurflour.com/...hurros-recipe
1Combine the water, butter, and salt in a medium-sized saucepan, heat until the butter has melted, and bring to a rolling boil.
2Remove the pan from the heat, and add the flour all at once, stirring vigorously.
3Return the pan to the burner and cook over medium heat, stirring all the while, until the mixture smooths out and follows the spoon around the pan; this should take less than a minute.
4Remove the pan from the heat, and let the mixture cool for 5 to 10 minutes. It'll still feel hot, but you should be able to hold a finger in it for a few seconds. If you have an instant-read thermometer, the temperature should be below 125°F.
5Transfer the mixture to a mixer, and beat in the cinnamon, if you're using it; then the eggs one at a time. The batter will look curdled at first, but when you add the last egg it should become smooth. Beat for at least 2 minutes after adding the last egg.
6Next, you have a choice of piping the batter into hot oil immediately, which will yield curved or S-shape churros; or piping it onto a piece of parchment and freezing for 30 minutes, which will make straight, stick-like churros.
7To pipe immediately: Pour a generous 4 cups vegetable oil (peanut oil preferred) into a 10" electric frying pan or heavy skillet set over a burner; the oil should be about 5/8" deep. If you use a smaller or larger pan, add oil to a depth of between 1/2" and 3/4".
8While you're heating the oil to 375°F, spoon the batter into a pastry bag fitted with a star tip. The star tip will give your churros their signature grooved surface. A 1/4" star is typically included in a basic pastry set; this will yield churros about 3/4" in diameter. If you're looking for fatter, 1" churros, use a wider star tip.
9Pipe a line of batter about 6" long into the hot oil. It's virtually impossible to pipe a straight line; you'll see. Pipe 5 or so churros at a time into the oil; don't crowd them, as they'll lower the temperature of the oil too much.
10Fry the churros for about 2 minutes on each side, until they're a light golden brown, and are cooked all the way through.
11Transfer fried churros to a paper towel-lined baking sheet to drain. Repeat until you've used all the batter.
12To freeze churros before frying: Pipe the batter in 6" straight lines onto a piece of parchment. Place the parchment on a pan, and put the pan in the freezer. Freeze churros for 20 to 30 minutes, until they're stiff enough that you can pick them up off the parchment.
13Fry frozen churros as directed above, about 2 1/2 minutes per side. Remove from the oil, and drain on paper towels.
14Sprinkle churros heavily with cinnamon-sugar, stirring gently to coat. Or spoon cinnamon-sugar into a plastic or paper bag large enough to hold churros without crowding, and gently shake, about 6 at a time, to coat with the sugar.
15Serve immediately. Or cool to room temperature, and store airtight for several days. Reheat in a 350°F oven for about 10 minutes before serving.
