recipe measurement question?

Question

Original recipe calls for:
2 1/2 cups self-rising flour
1/2 cup all purpose flour
1 tsp baking powder
1/2 tsp salt

I do not have self rising flour...
The "tip" said if you don't have self rising flour, use 1 cup flour, 1 1/2 tsp baking powder, 1/2 tsp salt = 1 cup self rising flour.

(The tip is for 1 cup self rising flour, I need 2 1/2 cups.)

MY QUESTION: What is the TOTAL amount of flour, baking powder, and salt that I need for this entire recipe? I only want to measure each ingredient once.

Is anyone better with numbers than me?? THANKS SO MUCH! :)

Answer 1

for the self rising flour you need:
2 1/2 cups flour
3 3/4 tsp baking powder
1 1/4 tsp salt

so total you need:

3 cups flour
4 3/4 tsp baking powder
1 3/4 tsp salt

Answer 2

for each one cup of self rise flour you need 1 cup flour, 1 1/2 tsp baking powder and 1/2 tsp salt. do that 2 times and on the thrid time cut it all in half. Simple

so you need 2 1/2 cups of flour, 3 3/4 tsp of baking powder and 1 1/4 tsp of salt.

Answer 3

Why not make up, say, 4 cups of the improvised self-rising flour? Measure out what you need and keep the rest in a jar or a ziplock for the next time.

Answer 4

2-1/2 cups flour
1-1/4 tsp salt
3-3/4 tsb baking powder

Answer 5

if you can't add fractions maybe you shouldn't be improvising your recipes
