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.
To make your own self-raising flour, add between 1 and 2 teaspoons of baking powder and half a teaspoon of salt for every 250g (1/2 lb) of all purpose flour.
1 cup of plain flour to bout 2 teaspoons of baking powder
For every cup of flour, add half a tablespoon of baking powder.
ie for 250ml flour, add 7.5ml baking powder.
1 1/4 tsp of baking powder/ 1/4 tsp. salt to every cup of all purpose flour
Self-rising flour has baking soda, baking powder and salt added in. All-purpose flour does not have these ingredients, so you have to mix them in if the recipe calls for them. For recipes that call for all-purpose flour, and you are using self-rising flour, you can leave these ingredients out.
Baking powder is baking soda with cream of tartar added to it.
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.
Self-raising flour already has baking powder and salt added to it in the packaging process. It's really just included for your convenience, and you can find plenty of muffin recipes that let you add your own baking powder so you don't have to buy self-raising flour specifically to make muffins.
No you don't, I thought this earlier on today, but if you have self-raising flour then you are fine. It just raises better with baking power added. Really you "must" use self-raising in using cake or will Not rise. :')
This is only a guide. Anything that needs to rise or uses self-raising flour. This is because if you do not have any SR flour you can use plain flour and baking powder. Also using baking powder you can control how much food will rise. This is especially useful for cakes as all ovens are different. Other recipes that may use baking powder could be scones and some biscuits.
No. Cornflour is made from corn and does not rise. It's used for different reasons than self raising flour which is wheat flour with bicarb already added. Be aware with cornflour that it can also be wheat flour if it says wheaten cornflour. That concept baffles me.
Self-raising flour recipesThis is low-protein, low-gluten white or wholemeal flour with a raising agent mixed in. The most usual raising agent added is baking powder, but some brands also use bicarbonate of soda or other agents.
yeast and baking powderActually, there is no yeast in self raising flour. Self raising flour is flour with bicarbonate of soda and cream of tartar (tartaric acid). This causes a double action rising effect. This is essentially the same as plain flour with added baking powder.
