You need a rosette iron to do this.
2 teaspoons sugar
1 cup milk (part half and half)
1 cup flour
1 tablespoon oil or 2 tablespoons melted butter
oil for deep frying
Make batter. Let sit covered, 2 hours in the fridge. Dip hot, oiled iron into batter, try not to get batter on the back of the iron, immerse in hot oil (370º) 1 - 2 minutes, just until golden brown. Rosette should slip off the iron with a little help from a fork, when brown. Drain on paper towels. Will store in airtight container for several weeks.
Sprinkle with powdered sugar. Serve with coffee.
