The Kitchen page shows open orders as cards in four columns, so the cooks can see what to do next.

Column	Orders in it
New	Pending orders that need confirming.
To cook	Confirmed orders waiting to be started.
Preparing	Orders being cooked now.
Ready	Orders ready to hand over.

Move an order forward with the buttons on its card. The screen refreshes itself every few seconds, so you can leave it open on a tablet in the kitchen.
