- Whisk or sift well. This helps distribute the baking powder evenly through the flour for a consistent rise.

How to Store Self Raising Flour
Homemade self raising flour is best used straight away, but you can also make a batch ahead and store it for later.
Transfer it to an airtight container or jar and keep it in a cool, dry cupboard away from heat and moisture. I like to give the container a quick shake before using, especially if it's been sitting for a while, to help redistribute the baking powder evenly.
For the best results, label the container with the date you made it and use it within 6 months, or before the expiry date of the flour or baking powder – whichever comes first.

Homemade Self Raising Flour FAQ's
Yes! Self raising flour is the UK spelling, while self-rising flour is the American spelling. Both are made from flour mixed with baking powder and sometimes a little salt, so they can be used interchangeably in most baking recipes.
No, baking powder is what gives self-raising flour its lifting power. If you don't have baking powder, it's best to use a recipe that calls for plain flour or wait until you can replace it, as baking soda alone won't give the same results.
To make homemade self raising flour, mix 1 level teaspoon of baking powder with every 100g of plain flour. Whisk well to evenly distribute the baking powder before using it in your recipe.
Homemade self raising flour will last as long as the baking powder stays active. Store it in an airtight container in a cool, dry place and use it within 3 to 6 months for the best rise. If your baking powder has expired, it's best to make a fresh batch.
Yes, but plain flour needs a raising agent. If a recipe calls for self raising flour, simply add 1 level teaspoon of baking powder to every 100g (¾ cup) of plain flour. Whisk well before using to ensure the baking powder is evenly mixed.
To test if your baking powder is still active, stir ½ teaspoon into a little hot water. If it fizzes and bubbles immediately, it's still fresh. If there's little or no reaction, replace it with a new container before baking.
