I am making Paella for 20 people but unable to purchase a paella pan at this time. What pan can I substitute ?. I was thinking of using a chafing pan since it's not very deep like a paella pan.
You can use about any pan that you could cook rice in. I've made Paella in a stock pot, hotel pan, and a Dutch oven. Honestly, the paella in the Dutch oven turned out better than it usually does in a paella pan. The heavy bottom of the dutch oven allowed for a much better layer of toasted rice at the bottom. For very large quantities a hotel pan is most convenient, but you may have better luck cooking the rice separately and tossing it together with the other ingredients at the end.
