BAKING SODA = - = - = - = - = - =  QUESTION    Which leavening agent (Yeast, Baking soda, or sourdough) will work best to leaven the bread)?    HYPOTHESIS    If I use baking soda to leaven my bread then the bread will rise the quickest.      MATERIALS    ● Mixing Bowl  ● 3 ½ All Purpose Flour    ● 1 teaspoon of Sugar  ● 1 teaspoon of Salt  ● 1 teaspoon of Baking Soda  ● 1 ½ cups of Buttermilk  ● Fork    RESULTS

NUTRIENTS   All purpose flour:    455 calories  95.4 grams of carbohydrates  .3 gram of sugar  12.9 grams of protein  133.75mg of potassium  Total fat: 1.2 grams     Sugar:    PROCEDURE    1. Preheat oven to 450° fahrenheit.  2. Place flour, sugar, baking soda, and salt into a large bowl and whisk together.  3. Pour buttermilk into the bowl, and leave ¼ of cup of it in the measuring cup. Use the fork as  a claw to move the flour together. Use the leftover buttermilk if necessary. Do not knead the  mixture.  4. When finished, scatter dough across a smooth  surface to make sure that the dough does not stick to  the table. Make the dough round and have a  thickness of 1 ½.  5. Make a mildly deep cross on the dough, but make  sure the cut is not reaching all the way to the edges  of the dough.  6. Bake for 15 minutes.  7. Turn down the heat to 400° and bake for 20-30  minutes more. When done, the loaf will sound  slightly hollow when tapped on the bottom and be  golden in color. One way to check if your bread is  done is to use a thermometer. Cook until  temperature in center reaches 195-200 degrees.            RESULTS

SOURDOUGH : COMMERCIAL =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=  MATERIALS    ● 1/3 cup sourdough starter  ● 1 scant tablespoon salt  ● 1 - 1 1/2 cup water  ● 3 1/3 cup white flour    PROCEDURE    1. Mix the sourdough starter, flour, and salt together.  Add 1 cup water and then more as needed to make a  moist bread dough.  2. Knead the dough until it passes the “windowpane  test” (about 20 minutes): a small piece of dough will  stretch  between 4 fingers without breaking thin enough to  allow light to pass through.  3. Shape the dough into a loaf. Place it in a pan,  proofing  basket, or on a board. Cover the dough lightly with a  towel and allow the dough to rise for 4-24 hours.  4. Slice an X shape in the top of the loaf with a very  sharp knife or razor blade.  5. Bake at 400°F for 30-60 minutes, depending on the  size of the loaf, until the internal temperature reaches  210°F. (Use a meat thermometer inserted into the  bottom or side of the loaf). Cool before slicing.    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

SOURDOUGH : DENNIS   MATERIALS    ● 1 tablespoon active sourdough starter  ● (1/2 cup) all-purpose flour or bread flour  ● (1/3 cup) water  ● 1 tablespoon salt  ● (2 1/2 cups) water    ● (5 1/2 cups) all-purpose flour or bread flour    PROCEDURE  1.

Make sure your sourdough culture is active.  2. Make the leaven (overnight.)  3. Test that the leaven is ready.  4. Dissolve the salt.  5. Mix the leaven and water.  6. Add the flour.  7. Rest the dough (30 minutes, or up to 4  hours.)  8. Mix in the salt.  9. Begin folding the dough (2 1/2 hours.)  10. Let the dough rise undisturbed (30 to 60  minutes.)  11. Prepare 2 bread proofing baskets, colanders, or mixing bowls.  12. Shape the loaves.  13. Transfer to the proofing baskets.      14. Let the dough rise (3 to 4 hours, or overnight in the fridge).  15. Heat the oven to 500°F.  16. Transfer the loaves to the Dutch ovens.  17. Score the top of the loaf.  18. Bake the loaves for 20 minutes.  19. Reduce the oven temperature to 450°F and bake another 10 minutes.  20. Remove the lids and continue baking 15 to 25 minutes.  21. Bake another 15 to 25 minutes.  22. Cool the loaves completely.  - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

CONCLUSION    To conclude, my partner and I believe that baking soda is the best leavening agent for bread  because we were able to see the rise in the dough and out of all the other breads that my peers  completed this was the fastest bread to make. This bread took a total of 38 mins to bake. We were  able to see the rise in bread within 15 minutes within baking. When we took the bread out we were  able to see that the bread has formed a tough crust on the top and surrounding the inner dough.  The taste was not as sour as expected compared to the other breads where we were able to taste  the acidity in the sourdoughs because of the fermentation. The bread grew a significant amount  while being in the oven. Before, our dough was 1 ½ inches tall, 7 2/8 inches wide, and 6 ¼ inches  long. After, the loaf was 3 ½ inches tall, 8 inches wide, and 7 ⅛ inches long. The overall increase in  total volume was 2 inches tall, 1 2/8 inches wide, and 1 ⅛ inches long. I think it’s clear to say that  baking soda ​is the right way to go when wanting to use a leavening agent in your next baking  project.     Citations:     - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
