Ciabatta Bread

This is my first attempt at making Ciabatta and, although the result was good, the original instructions were not very good, and I'd like to experiment with other recipes, just for fun. This is one of these recipes that take a long time! I didn't read the instructions carefully and missed the fact that the bread had to rise a second time for 90 minutes, and I was making the bread for a sandwich for a birthday party we were going to, and I barely had time to make it! But I persisted, just because I said I was going to make it and I would not have been satisfied with just buying something, and even though I panicked I was able to make it with, literally, 5 minutes to spare!

Biga (starter)

1⁄4 tsp instant dry yeast

1 cup water, at body temperature

1 1⁄4 cups flour

1. Dissolve yeast in warm water.
2. Mix in flour by hand and stir just until there are no lumps. The mixture will be very wet and sticky.
3. Cover and refrigerate for at least 12 hours.

Bread

1 tsp instant dry yeast

3 Tbsps milk, at room temperature

2⁄3 cup water, at body temperature

1 Tbsp olive oil

2 1⁄3 cups all-purpose flour

1 1⁄2 tsp sea salt

cornmeal, for baking tray

1. Stir the yeast and warm milk together in the bottom of the bowl of a standup mixer fitted with the paddle attachment. Add the warm water, oil, and the starter, and mix with the paddle until blended (or the dough can be mixed by hand in a bowl with a wooden spoon but be forewarned, it is very sticky).
2. Switch to the dough hook and add flour and salt, kneading on low speed for 2 minutes, then, increasing to next speed up, knead for 3 minutes. Slap the dough with your hand in the bowl, until it feels stretchy and springs back (it will be too sticky to knead on a work surface).
3. Place dough into an oiled bowl, cover bowl with plastic and set in a draft-free, warm area to rise for about 90 minutes. The dough should have lots of big air bubbles visible when ready.
4. Measure out parchment paper that will fit into a large baking tray and liberally and evenly sprinkle with cornmeal (do not put in baking tray yet - the baking tray has to heat up in the oven before putting the bread on). Turn dough out onto a lightly floured work surface and roll up into a cylinder (like you would for a loaf or bread), but then stretch and pull the flexible dough into a rectangle about 20 inches by 8 inches. Cut dough in half and place each on parchment-lined baking tray. Cover loaves gently with a slightly damp tea towel and let rise another 90 minutes.
5. Preheat oven to 425°F and place a baking tray upside down in oven to heat. Remove the hot tray from the oven, and slide the parchment with the bread onto hot tray and return to the oven quickly. Spray tops of loaves with a little water, close oven quickly and bake for 20 to 25 minutes, spraying again with water after 10 minutes. Remove the bread from the tray to cool before tearing or slicing.
