Teflon is fine....or any shallow pan is fine.....
Linda C

You probably already know this, but when you're flambeeing something the easiest way to get it to catch is to heat up the sauce, take out a little of the sauce in a metal spoon, heat THAT up and flame the spoon's contents, then return the flaming spoonful to the pan to ignite the rest of the sauce.

Thank you for your responses. It's been a long time since I've flambeed anything so I appreciate the advice given on how to flambee.
