Ana's NY Bialys

1. Stage

Preheat oven to 200 degrees F (95 degrees C). Turn off and keep door closed to retain warmth.

2. Stage

Dissolve yeast and sugar in 1/2 cup warm water in a large bowl. Let stand until yeast softens and begins to form a creamy foam, 7 to 12 minutes.

3. Stage

Mix all-purpose flour, bread flour, vital wheat gluten, and 2 1/2 teaspoons salt in another bowl; add to yeast mixture. Combine remaining 1 1/4 cup warm water with onion juice; pour over flour and yeast mixture. Stir together until a dough forms.

4. Stage

Knead dough on a floured work surface until soft and smooth, 8 to 10 minutes. Form dough into a ball and place it in a lightly-oiled glass or ceramic bowl, turning to oil all sides. Cover with a towel. Place dough in warm oven until it triples in bulk, about 1 1/2 hours.

5. Stage

Punch dough down and turn it over. Cover with plastic wrap and let rise in the oven again until doubled in bulk, about 45 minutes more.

6. Stage

Punch dough down again and transfer to a floured work surface. Divide into 2 equal cylinders. Slice each cylinder into 8 rounds. Lay them flat and let rest, covered with a towel, about 10 minutes.

7. Stage

Heat oil in large skillet over medium-high heat. Add onion and cook, stirring often, until golden, about 5 minutes. Remove from heat; stir in poppy seeds and 1/2 teaspoon salt. Let filling cool to room temperature.

8. Stage

Flatten the dough into rounds about 3 1/2-inches in diameter with a raised middle and thinner edge. Sprinkle cornmeal lightly over 2 baking sheets. Arrange dough rounds on baking sheets. Cover with plastic wrap and let rise until increased by half, about 30 minutes.

9. Stage

Center oven rack and preheat oven to 425 degrees F (220 degrees C).

10. Stage

Press the bottom of a greased shot glass in the center of each round to make a deep indentation. Place 1 to 2 teaspoons of filling in each indentation. Cover with plastic wrap and let bialys rise until puffy but not doubled, about 15 minutes.

11. Stage

Bake bialys in the preheated oven until lightly browned, rotating the baking sheets so they brown evenly, about 15 minutes.
