Why do you need to preheat the oven before baking bread?

This is necessary. All recipes in the pastry industry are made into recipes. After repeated trials, the baking conditions, that is, time and temperature, are stipulated, and then they are promoted to scale production. For example, my company is nationwide Hundreds of stores use the same recipe. If the oven is not heated to a predetermined temperature in advance, large-scale production will not be possible.

1. Assuming that the oven can bake good snacks without preheating, the room temperature in different places is different. How to ensure the baking time and quality will become a big problem.

2. There has been such an experiment. The process of putting snacks in without preheating and baking them slowly until cooked has the following results

Even if the baking time is extended for a while times, or longer, the bread in the oven is not baked to the desired effect, and the energy consumption is greater

During the heating process in the oven, the bread continues to rise due to the slower heating process, which in turn leads to Excessive proofing, the skin cracks, and the volume shrinks after baking

The bread skin has no luster.

If it is made into a cake, the cake will be difficult to expand in volume, outgassed excessively, and the structure will be tight. .

If it is an egg tart, the egg tart water will soak through the pastry at the bottom, making the outside of the egg tart not crispy, and it will feel like eating dough

If it is biscuits, cookies will As a result, the oil in the tissue will not be able to effectively combine with other materials, causing problems with the biscuit structure

...

You can imagine that if you cook, the result will be After the oil is put in, the vegetables are poured in. How do you want to fry your vegetables?

How to preheat toasted bread 5 minutes

Read the instructions for your oven.

I have never seen an oven with only one tube, so there must be one at the top and one at the bottom.

Otherwise, how can you control your upper and lower fire?

Preheating means hanging the bread in the oven for heating. Generally, bread is placed on the baking sheet and put in together after preheating.

What is preheating when toasting bread? Is it a function on the oven or something?

After the bread is made, it needs a period of proofing. When the proofing is completed and the fermentation is in place, it can be baked in the oven. At this time, the temperature in the oven is required to reach the specified baking temperature, and the difference cannot be too large (the error is 5 to 10 degrees). If the oven has not been turned on before, the temperature will be close to room temperature, and the temperature difference will be large (a difference of 200 degrees). This cannot be used to bake bread. When the oven temperature rises to the appropriate temperature, the bread will have over-risen. Therefore, it is necessary to open the oven in advance before the final fermentation of the bread is completed, so that it can meet the needs of baking the bread (also consider Energy saving and consumption reduction issues), this preheating behavior process is preheating.

Bread machines do not seem to have this problem. Due to program control, this process will be completed automatically.

Why do you need to preheat bread when making bread?

Prevent the bread from sticking to the mold and preventing the bread from being undercooked. Do not apply too much oil on the mold, otherwise it will be difficult to remove after baking.

Does the oven need to be preheated before baking the bread?

Necessary, just like hot oil before stir-frying

Otherwise the dough will deform in the slowly heating oven, or even explode on the surface.

How long does it take to preheat the oven for baking bread?

Preheat the oven to 180 degrees for 15-20 minutes before placing the bread.

If you want to know more specifically how to test the taste of bread: the upper and lower heat are both 180 degrees, but you have to put down the lower layer to bake, otherwise the texture and flavor will be gone. Wait next to it for 15 minutes. Once the test is done, It's ready to be taken out.

In fact, there are some on Baidu posts. It is best not to post questions that others have posted.

How long does it take to preheat a bread oven?

It depends on the specific model, size, and type. It takes 5-7 minutes for household use to reach the basic baking temperature, and for commercial use, it takes 7 minutes to reach the basic baking temperature. The oven takes more than 15 minutes, but generally speaking, an oven that heats up slowly will also cool down slowly (the efficiency of maintaining temperature is better).

Does the oven need to be preheated before baking bread?

Yes, just like you need to heat oil before cooking.

Otherwise, the dough will be heated slowly in the oven. Deformation, even surface explosion.

Why is the bread baked in the oven so dry

LZ The main reason for the situation you mentioned is that the baking temperature is not controlled well. The heat is too high, which causes the skin to be over-baked and becomes "hard"~

Baking bread: Preheat the oven to 180°C.

Brush an even layer of whole egg liquid on the dough that has completed the final fermentation. Do not use too much force when brushing with egg wash, as the fermented dough will deflate and collapse. Place the baking sheet in the upper middle of the oven (if the oven can be divided into upper and lower heat, then the upper heat is 180°C and the lower heat is 150°C) and bake for 15-20 minutes.

In addition, you can also place a cup of water in the oven to increase the humidity in the oven and prevent the bread crust from drying out due to high temperature.

Depending on your materials, you can make ordinary bread. Sweet bread. It's best to add butter, which is butter.

The steps for making bread are a bit complicated. The following is my experience. I use the tangzhong method, because the bread made with tangzhong is much more delicious than the direct method, but it only has one more Steps can save you some detours. Hope it helps.

1. Tangzhong

Tangzhong is easy to make: 1 part flour, 5 parts water, mix together and stir until there are no particles, heat over low heat to 65 degrees and remove from heat . Stir continuously during the heating process. When you see small bubbles forming on the edge of the pot, the batter continues to thicken and leaves traces of stirring, you can remove it from the heat. Cover with plastic wrap and cool to room temperature before serving. Or refrigerate until use the next day for better results.

The soup made with 20 grams of flour and 100 grams of water can be used to make bread once. Tang Zhong made from 50 grams of flour and 250 grams of water can be used to make bread three times.

2. Knead the dough

Let’s use the ratio of ordinary sweet bread as an example, because this recipe can be changed in many ways. As long as different fillings are added, it will have different flavors. bread.

210g high-gluten flour, 56g low-gluten flour, 20g milk powder, 42g fine sugar, 1/2 teaspoon salt, 6g dry yeast (you need to make a little according to different brands of yeast and flour) Adjustment)

30g whole eggs, 85g water, 84g soup.

22g unsalted fermented butter

1. Mix all dry ingredients except yeast.

2. Add egg liquid and soup seeds, stir slightly to make the dough form a ball.

3. Completely dissolve the yeast in the water and add to the dough.

4. Knead the dough. The focus of this step is to continuously fold and squeeze the dough until the dough becomes chewy and no longer feels grainy.

5. Add butter in batches and continue to beat and knead the dough. The goal is to expand the kit stage: by pulling off a small piece of dough, the slightly transparent film can be pulled apart, and the holes will be jagged.

The dough before adding butter is very sticky, which is normal. Do not add more flour. If it is too sticky to handle, the soup may be too thin. The butter must be added in batches, kneading it evenly before adding it each time. As the dough becomes oily, it will gradually become smooth and no longer sticky.

3. Basic fermentation

1. Gather the dough into a smooth ball. In this step, just put the dough on the table, use your hands to circle around the table, and push the bottom of the dough at the same time, and you will have a beautiful ball.

2. Find a large bowl and put a layer of oil in it, just as thin as necessary, so as not to make it difficult to take out the dough after fermentation.

3. Cover the lid or seal with plastic wrap.

4. Find an environment with a temperature of 28 degrees and a humidity of 75 degrees to allow the dough to ferment until it doubles in size. It takes about 45 minutes.

You can turn on the oven or microwave for 30 seconds, turn it off, and just reach out and feel a little warmth. Be careful not to touch the inner wall of the oven with your hands. Even if it is only turned on for 30 seconds, it will be extremely hot.

If the room temperature has reached 28 degrees, also add a cup of water to increase the humidity.

4. Divide and relax

Take out the dough and cut it into required portions. When cutting, it should be done with one cut, and you can't cut it up and down, so try to cut it into the same size.

After dividing, roll each small portion of dough into a round shape. Also put it on the table, wrap your hands around it, and twist and tighten the fingertips while exerting force toward the bottom of the ball. Then cover with plastic wrap and rest for 10 minutes.

5. Plastic Surgery

Be sure to exhaust air before plastic surgery! ! This step is to flatten the relaxed dough and expel the air. Then you can perform the shaping as required. There are many ways to shape bread, such as braided bread, flower-shaped bread, etc. You can also use your imagination.

6. Final fermentation

The final fermentation conditions are a temperature of 38 degrees and a humidity of 85 degrees. The dough must also be doubled in size. I filled a large salad bowl with boiling water, it was still less than 35 degrees, but it was okay. The time is about 30 to 45 minutes.

After the final fermentation is completed, you can preheat the oven (preheating may take 15-25 minutes depending on the oven).

Brush the surface of the dough with a layer of egg wash, sprinkle with nuts or coconut as you like...

Be sure to preheat before baking.

Yes, preheating is a necessary process for baking
