Is There an Alternative to Ramekins for Baking Souffles?

Hello all.

I am planning to bake my very first soufflés and I am wondering if I can bake them in something other than ramekins. I'm sure there is a very good reason why the ceramic ramekins are the standard (in my estimation they might be the best for heat distribution) but I am wondering if I can make do without them.

Can I bake them in muffin tins, for example?

I should note that the first ever chocolate souffles I had were served in little foil tins. I surmise they were baked right in these tins. These souffles didn't seem 'authentic' (in my mind) by any stretch but they tasted good. I doubt any bakery would sell their souffles in (expensive) ramekin dishes.

So do you think I can get away with making souffles without the ramekins?

(I do plan on getting ramekins in the future.)
