About 1.5 teaspoons. If the recipe calls for self raising flour and you don't have any then add 1.5 teaspoons of baking powder and 0.5 teaspoons of salt.
You can but you need to add baking powder and salt to it.
Most recipes use 1 teaspoon of baking powder to 1 cup of flour.
There is not a standard amount - it varies according to what you are cooking. If you wish to turn plain flour into self-raising, you need baking powder (which is a 1:3 ratio of bicarbonate of soda to cream of tartar). You need one teaspoon of baking powder to a cup of plain flour to create self-raising flour.
Yes. But add twice as much. When you use self-raising flour, add 1 tspoon of baking powder, to lighten the cake. So just add about 1 tbspoon if using plain flour.
I don't know how much volume 4 oz. will be, but most recipes use the ratio of 1 teaspoon of baking powder to 1 cup of flour. Weigh the flour, measure it and find the amount of baking powder that way.
2 grams
One to one and a half teaspoons of baking powder and a pinc to one half teaspoon of salt to a cup (125 g) of flour.
What do you think?
Generally you use 1 to 2 teaspoons of baking powder to each cup of flour.
About one teaspoon of baking powder to 1 cup of all purpose flour
The amount of baking powder required depends entirely on what you intend to bake. Different types of cookies, muffins and other baked goods require different proportions of baking powder to flour.
None. Recipes calling for self rising will also call for salt. The only thing self rising has in it is baking powder. If you notice, most recipes use the ratio of 1 teaspoon of baking powder to 1 cup of flour. This is a common ratio, but some recipes can have more or less depending on what you are making.
