This classic Chinese-American takeout dish, despite the name, has nothing to do with Mongolian cuisine and actually originated in Taiwan. This sweet and savory meal is a family friendly favorite. We’ve added a touch of cayenne pepper for a little spice, but you can omit it to keep it more traditional.

Silly question and more double checking that I’m reading this correctly but do both top and bottom sections need to be at 120 for 2 hrs if only the top has the food?
Just learning!

I have to say I am very annoyed to realize that at the very moment after the steaks have finished the initial cooking to realize it is calling for 2 roasting racks when I only got one with the pans!!!!
