Sorry but if the recipe calls for it you need both
Baking powder is composed of:
baking soda + two dry acids
When exposed to heat it will react ONLY with itself to create gas to help the baked product rise.
Baking soda is just baking soda:
It reacts with an acid ingredient in your recipe when exposed to moisture which produces gas. Without the acidic ingredient the baked product will taste soapy or bitter, and without the baking soda your baked product will taste sour.
Acid Ingredients include (but are not limited to):
buttermilk
vanilla
lemon juice
Baking powder is activated in the presence of moisture and heat. Baking soda is activated in the presence of acid. Baking soda is often used in recipes which include fruit or fruit products (stewed apple for example) because these are acidic (sour).
In recipes which include normal cake ingredients (butter, eggs, sugar, flour) and also some fruit you may find that the volume of baking powder is reduced and replaced with some baking soda. Since baking soda is already added to baking powder it is not strictly necessary to do this, but failing to do so may effect the height to which the cake will rise.
Other recipes - like sticky toffee pudding, hokey pokey, or brandy snaps require you to add baking soda to wet ingredients you have previously heated in a pot before adding this to the other dry ingredients. The mixture will froth up in the pot releasing carbon dioxide - but more will be released during the cooking process. It is important that you follow this step and do not replace the baking soda with baking powder.
Yes it aids in the rising. When a recipe contains baking powder and baking soda, the baking powder does most of the leavening. The baking soda is added to neutralize the acids in the recipe plus to add tenderness and some leavening.
Well if your recipe calls for 1 teaspoon of baking soda, you would need four teaspoons of baking powder to produce the same amount of lift.
Baking powder and baking soda are often used together in recipes in order to add lift to the final product. Because baking soda is a base and commercial baking powder is generally slightly acidic, they are often used together to neutralize both each other the other ingredients of the recipe. Yes baking powder and soda can both be used in the same recipe.
baking powerder is baking powder is not the same!
Baking powder is a mixture of baking soda, starch and an acid (often tartar) to activate the baking soda. Since baking soda is already in the baking powder, it is possible you will not need any additional baking soda. Baking powder and baking soda are used to "raise" or puff up the pastry - too little and it will not raise properly...too much and it will taste like soda. If you do not have a specific recipe, you will need to experiment.
Baking powder and baking soda both act as a leavening agent. They would do the same thing
Me and my science partner Anita had the same problem and it turns out you can but you'll need to use four times as much baking powder then baking soda.
No. Baking mix (such as Bisquick) contains flour, baking powder and other ingredients.
Baking Powder is what makes cakes rise, similar to yeast in bread. Plain flour recipes usually need baking powder added alongside other ingredients, whereas Self-Raising flour already has Baking Powder combined so extra is not usually needed. If you bake cupcakes with Plain flour and without Baking Powder they will be very flat, about the same size as the raw mixture, it won't be light and fluffy but quite dense. It is also a good idea to not substitute Self Raising flour in a recipe that calls for Plain and Baking Powder (and vice versa), as the amount is usually tailored to give just the right amount of rise to the food.
No. Baking powder contains baking soda along with an acidic ingredient and salts.See : http://video.answers.com/baking-soda-vs-baking-powder-290159125
Baking powder and baking soda are not directly interchangeable. If baking powder is used, one should reduce the amount of salt in the recipe, as well as reduce or eliminate any added acidic ingredient such as vinegar or lemon juice; replace buttermilk with regular milk.
There isn't one. Bread Soda is the Irish name for baking soda.
