Without a professional fermentation box, the temperature and humidity of bread fermentation can still be controlled!


Abstract

Making bread involves two fermentation processes, and recipes often specify conditions for each. The first fermentation typically requires a temperature of 28-32℃, which is easily achieved at room temperature. Even if the temperature isn't quite right, extending the fermentation time can compensate. At this stage, the dough hasn't been shaped, so simply covering it with plastic wrap or a damp cloth provides sufficient humidity.

  Making bread requires two fermentations, and we always see that the recipe has requirements for the conditions of the two fermentations. The first fermentation generally requires a temperature of 28-32℃, which is easy to manage; it usually ferments at room temperature. Even if the temperature is not reached, it can be solved by extending the fermentation time, and at this time, the dough is not shaped, so it can be covered directly with plastic wrap or a damp cloth to create sufficient humidity.

  The second fermentation is more difficult; it generally requires a temperature above 35℃ and a humidity above 80%. Households do not have professional fermentation boxes, so what should we do to achieve these conditions? Since professional tools cannot be used, let's use some alternative methods. Although they are not precise, they are very effective.

  During the second fermentation, the dough is usually shaped and placed on a baking sheet. At this time, place the baking sheet in the middle or upper layer of the oven and place a pan of hot water at the bottom of the oven. Close the oven door. The oven has a certain airtight effect, and the hot water pan at the bottom will continuously emit water vapor, creating sufficient temperature and humidity inside the oven.

  Here are a few points to note:

  1. A thermometer and hygrometer are good helpers. Placing it in the oven allows you to know in time whether the temperature and humidity in the oven meet the requirements, and flexibly adjust the temperature and amount of hot water you put in.

  2. If your oven has a low-temperature fermentation function, you can use this function to keep the oven at a constant temperature. If not, you may need to replace the hot water with a new pan of hot water when the hot water in the oven cools down.

  3. This is a fermentation method suitable for home use. Because of this, it cannot control the accurate temperature and humidity like a professional fermentation box. We only need to ensure that the temperature and humidity are within a general range, and we don't need to require it to precisely reach the level required in the recipe.

  Without using any chemical additives, using only natural ingredients, you can make healthy and delicious desserts at home.
