Double 2/3 cups

[schauvi]

What would I get if I wanted to double 2/3 cups?

[Andy M.]

1 1/3 cups

2/3 + 2/3 = 4/3 = 1 1/3 just as Andy said.
I think you've forgotten your 5th grade math.

Hello and welcome to DC. Andy is right if you double 2/3 cups you would get 1 1/3 cups.

I don't bother to do the math. If I am doubling a recipe, I just put everything in twice. For some recipes, it's better to make two separate batches. Especially for those where you would not double the liquid as in some casseroles.

...or where you don't want to double the seasonings/herbs.
