How do I wrap a spring-form pan in foil so it doesn't leak when I bake in a water bath? I have never found a spring-form pan that does not leak.

I have never been able to wrap a spring-form pan so that some of the water doesn't get into the pan.

I can wrap it so that a lot of the water doesn't come into the pan.

But it seems to me that there must be a method that works to keep the water out entirely.  I just haven't figured it out.

How can I wrap a spring-form pan in foil so that water from the bath doesn't leak into it?
Cook's Illustrated recently discovered that placing the springform pan inside a slightly larger cake pan works. The slight air gap doesn't negate the water bath's benefits. And of course a cake pan is a solid piece of aluminum, thus completely water tight.

(Haven't personally tested this yet.)
