Are they real onions on white castle burgers?

Answer 1

White Castle uses dried, minced onions. They re-hydrate them and spread them on the flat top grill. They place their Hamburgers over the top...the reason for the tiny holes in each "burger" is that they literally steam them on a flat top using the minced onions to do the job. Maybe you've heard they use cabbage. Not true. To duplicate that one of a kind taste, buy dried minced onions and rehydrate them with a bit of water....use a flat top grill or griddle...make the burger tiny and thin and with small holes to in effect steam them.
