Have you ever noticed how onions can be many sizes ? 1 chopped onion could be 0.5 cup to about 1.5 cup
I'd go with about 8-10 cups of onion per 48oz batch
Depends on what type of onion; for a regular large white onion, I would say one large one would be sufficient. If it's a smaller (e.g. yellow or red) onion you might want to go with 2 or 3 to be sure.
i dont know maybe 11
many
For example, if your toppings are tomato and onion, you could have one burger with tomato, one burger with onion, and one burger with tomato and onion.
That is 9 one third cups.
how many cups of water in a liter
2 cups
Six cups
That would depend on the size of the raw onion!
4 cups in a quart and 2 in a pint
About 1.5 cups
