Does baking soda expire?

anotherjennifer | Sep 5, 201011:23 AM     9

There's a "best by" date on my baking soda. I made a honey cake yesterday and it fell after it came out of the oven. Now it has a giant trench in the middle. IIRC, this happened last September, too. I had double checked the "best by" date on the baking powder yesterday when I was baking and that was fine, but somehow never looked at the baking soda. The recipe called for both.

I just looked now. The best by date was, ummm, July 2009.

DH thinks baking soda doesn't really expire because there's nothing to expire and they're just legally required to put some sort of date on it and it's probably not the problem with the cakes.

So, toss the baking soda and figure the cake will work better next year or go looking for another culprit?
