I plan to make a BIG pot of onion gravy soon. Is there a rule of thumb about the volume and weight relation of sliced onions?
So, my big pot holds about 12l - I’d go for 10l here to have room to stir - if thinly sliced on a mandolin, how many kilograms of onions would that be?
Or, the other way round, if one slices a kilogram of onions, how much volume would that fill?
I know how to cook that gravy, that’s not the issue. But usually, I take a “normal” pot, chuck in a few onions, and have gravy for a few servings and for the fridge. Pot space was not the issue.
This time, I want to go big. I know that the onions shrink, so what I need to know is with how much onion I should start to get to the stated 10l limit to have enough headroom to stir the stuff.
Beef shrinks up to 1/2, and onions also shrink up to 1/2 depending on heat.
Should be easy to figure out.
It’s not the shrinkage I’m worried about. I know it shrinks. The question is how many kilos would I have to put through the food processor without the pot flowing over.
Okay…so…do the math I just gave.
