I've been trying to make bread for years and have not had much success. Recently I thought I would get "scientific" and read a couple of books on the science of cooking. I've learned that yeast is the key to rising, AND the SOLUTION the yeast is prepared in is KEY! I've tried different things with yeast and noticed a difference in the amount of foam/bubbles formed in the cup I prepare my yeast in. As it turns out, the more foam/bubbles in the "yeast water cup", the better the bread will rise. Today I made my best batch of "yeast water" ever! Higher foam/bubbles than ever before! I'll explain it step by step as each step is quite important...(Instructions below) I use a 2 cup size glass measuring cup because it is easier to mix in the ingredients. Then I add a small bit of filtered water from the refrigerator to the cup. This is so the addition of corn syrup will not stick to the bottom of the cup and be easier to stir in. And filtered because it removes the chlorine from the water. My thinking is that the chlorine in city water might kill the yeast? And the water is at a specific temperature, thus I can heat it for a specific time in the microwave and get a specific temperature. Then I add 1 tablespoon of corn syrup to the cup. This has "fructose" in it and is food for yeast, makes it grow. Then I fill the cup up the rest of the way with filtered refrigerator water to be 1 1/4 cup of water. (This is the amount of water needed for 3 cups of high protein bread flour which will say 5g protein on the label instead of the 3g protein on "all purpose" flour. Yeast needs protein to grow. High protein flour needs more water.) Then I mix the water to blend in the corn syrup. Then heat for 65 seconds in my 1000 watt microwave. This brings that amount of water at my refrigerator temperature up to a little over 125° F. and this is the temperature yeast needs to be to grow. Measure the temperature with a candy thermometer to be sure you get this temperature. "Warm" as it says in cookbooks does not cut it! Make sure it is this exact temperature! Then I add 1/2 teaspoon soy lecithin. This I got at a health food store as bulk lecithin granules and this helps yeast to grow. Then I add 1/8 teaspoon citric acid. Yeast likes a slightly acidic solution. I also got this at a health food store in the bulk section. Then I add 1/8 teaspoon ginger. I read this has some ingredients which yeast likes. Then I add 2 packets rapid rise yeast. (I read that the drying process kills yeast, so I figure 2 packets is better!) Then mix it all up well. Wait a few minutes, and there will be about 1/2 inch to 1 inch of foam/bubbles in the top of the cup! And this is what yeast needs to do to make the bread rise - make gas/foam/bubbles. And my bread raised twice as fast as my previous batch of yeast water which only had 1/4 inch of foam/bubbles. So I think foam/bubbles in the yeast water concoction is the key... Yeast Water Recipe Use “2 cup size” measuring cup. Add a bit of refrigerator water to cup. Add 1 tablespoon corn syrup to cup. Fill cup with refrigerator water to make 1 1/4 cup liquid. Heat cup in microwave 65 seconds (125°), mix. Add 1/2 teaspoon soy lecithin. Add 1/8 teaspoon citric acid. Add 1/8 teaspoon ginger. Add 2 packets rapid rise yeast, stir. Wait a few minutes and should get at least 1/2 inch foam (if not try again!).
