Yeast. Oh dear, yeast. You know those problems I had with cake? Imagine them tenfold, with yeast. For most of my cooking life, anything I made with yeast came out like a rock. It never rose! I eventually decided I must be cursed.
Then one day my sister asked me something very simple. "Don't you bloom the yeast?" she said.
Bloom? What was this strange ritual? And with these instructions, my baking horizons opened. Ever since I learned of this procedure, I've not had a yeast recipe fail. Blooming is something referenced in older cookbooks, but it seems to have disappeared from most non-specialty books over the last few decades. This is because commercial yeast is generally good - meaning it's alive when you buy it - and can be trusted to work. But blooming is more than just making sure your yeast is alive. It also gives a kickstart to the leavening process, allows flavor to develop, and makes it easier to combine the dough.
So here's what you do.
First, get the milk or water for your recipe hot. I'm making bolillo rolls; I need just over one cup of water. Mix it with the sweetener from your recipe; for this, I'm using honey, which is why the water is yellow. You must use some kind of sweetener when using yeast: it's what the yeast eats! Then, stick your thermometer in the liquid and water, and check to see that the temperature is about 90-105 degrees Farenheit (32 to 41 Celsius.) It is really important to get the temperature right: yeast dies at 120 degrees F (50 C) - and you don't want to kill the poor little yeast!
The next step is to sprinkle your yeast on top. Some people say to mix it in, some don't; I've never noticed a difference, so I just let it sit. Cover the bowl with a tea towel and let it be. Seriously, leave it alone for at least five minutes. You can walk away, or you can do what I do, which is to sing the yeast a little song.
Grow little fungi!
Grow grow grow!
Bubble and fart, fart and burp
Grow little fungi!
Grow grow grow!
Ahem. Anyway, after five minutes, your yeast should have gone from looking dry and grainy to soft and pillowy. The one on the top is the yeast just after adding; the one on the bottom is the bloomed yeast.
After this, it's really simple. Add your flour, add your salt, and whatever else is in the bread. Bolillo rolls have oil which makes them very soft and pliable. After the dry ingredients are added, the dough will look "shaggy." Really, you'll know it when you see it. Different recipes have different instructions for how long to knead and let the dough rise, so be sure to check your recipe. The recipe below is for bolillo rolls, which are great for pretty much everything, including eating on their own.
Bolillo Rolls
2 1/2 cups flour
1 cup plus 1 tsp warm water
1 1/2 tsp yeast
1 1/2 tsp honey
1 tsp salt
1/4 cup vegetable oil
1/4 cup water mixed with 1 tsp salt, for brushing
Cornmeal
Baking pan and boiling water, for the oven.
Prepare your baking pans with parchment paper sprinkled with a little amount of cornmeal.
Follow the instructions above to bloom the yeast. After the yeast is bloomed, mix in the flour and salt; when mostly combined, add oil and mix until "shaggy." (You will know it when you see it!) Turn the dough out on to a floured surface and begin to knead. Knead the dough for about ten minutes, until it comes together in a ball.
Put the dough back in the bowl, cover, and let rise in a warm place for about one hour, or doubled in bulk. It will look something like this:
Bolillos are a very soft, airy roll, so handle the risen dough gently. Don't punch it down - just turn it out on a lightly floured surface and shape into a circle. Cut the dough into eight more or less even peices. Shape each piece into a circle, then fold the circle in thirds. Roll the dough until it looks a bit like a flattened football, like these:
Put them on the prepared baking pans and let rise for about another hour, until again doubled in bulk. About halfway through the second rise, turn the oven to 425 degrees to preheat. Put the baking dish with boiling water on the bottom rack of your oven (this will create steam.) Then brush rolls with the saltwater mixture, and cut a slash in the top of each roll.
Bake for fifteen minutes, or until they are the golden color you like best. These keep quite well.
