"Editor, editor, why is my sugar pie unsuccessful?
everyone can swell with fans, why can't I do it?"
img0 span1 , The hit of the Korean drama " squid game " really brought this product into flames - .
Speaking of puff, it actually originated in our Greater China. To put it simply, boil the granulated sugar into caramel, add baking soda and stir, then you can eat it~
is like last year's "Cameiro", which was very popular last year. It is also the same product.
that you as baking enthusiasts,
if thought about this question:
Why do use baking soda instead of sugar Peng Where's baking powder?
Today we will learn some details about baking powder and baking soda.To help you understand the difference more completely and carefully!
Chemical properties
Although the chemical properties of baking powder and baking soda are different, they are different in chemical properties. .
Baking soda is also called baking soda or sodium bicarbonate , chemical formula: span3 COspan _span NaH.
When baking soda (alkali) is used in the formula, it usually contains certain acidic ingredients. When baking soda (alkali) and vinegar (acid) are mixed, a chemical reaction occurs, and the product of this reaction is carbon dioxide. The chemical equation is as follows:
NaHCO3+H+=Na++H2O +CO2↑
If we bake our biscuits, cakes, and bread recipes if they contain: buttermilk, brown sugar, yogurt, lemon juice, vinegar, tartar, syrup Applesauce , natural cocoa powder (non-Dutch craft) or honey, etc. will have such a reaction.
Baking soda will also produce carbon dioxide when heated. The chemical equation is as follows:
2NaHCO3=CO2↑+H2O+Na2CO3
Baking powder is a mixture of baking soda, tartar cream (a dry acid) and corn starch.
Nowadays, most baking powders are double-acting. This means that the first swelling occurs when the baking powder gets wet, and the process is like when you mix dry powder and wet powder together. The second expansion occurs when the baking powder is heated.
Because baking powder contains an acid to neutralize the baking soda, when a formula does not contain other acidic ingredients, we can use baking powder. Even in formulas with acidic ingredients, we can still use baking powder as a bulking agent.
Use a mix of the two
_p _p _pUsually these formulas contain some kind of acid (yogurt, brown sugar, etc.), but the carbon dioxide produced by the acid and baking soda is not enough to swell the batter in the formula. At this time, baking powder needs to be added to enhance the expansion of the dough.
Another reason for using baking powder and baking soda at the same time is that they will affect the color and taste of the dough at the same time.
use it instead of both
span soda powder. Notice! You only need to use 1/4 of the original amount of baking soda to get the same amount of expansion .
The premise is that more acidic ingredients need to be added during the baking process, which may change the taste and texture of baked goods.
Therefore, in the baking process, we try to follow the recipe quantity and steps, and try not to substitute other ingredients.
How to detect activity
-check the baking powder in a small bowl of water _span 45-_span strong -check the baking powder-_spanstrong Add 2.5g baking powder and stir gently.
If the baking powder is fresh, the mixture will foam moderately. If there is no response, you can replace the baking powder with a new one.
-test baking soda-
Pour 45ml of distilled white vinegar in a small bowl, stir gently with 2.5g of baking soda.
If the baking soda is fresh, this mixture will foam quickly. If there is no response, replace with new baking soda.
The operation steps of puffing sugar
1. Add the white sugar to a small spoon without adding a large soup spoon.
2. Keep stirring until the sugar has melted, and when it is browned at about 120~130℃, quickly add a little baking soda, continue to stir quickly, and observe the syrup expansion.
3. Pour the syrup on baking paper,Cool for about 10 seconds.
4. Spread another piece of baking paper on the syrup, flatten it with a tool, quickly tear off the baking paper, and press out the pattern with the prepared mold.
