This year I saw a can of Libby's pumpkin pie mix at a discount strore... 30 oz ... and thought ... hmmmm, wasn't that once 32 oz?
I mentioned this in another post, and someone wondered if it was true. Googling there are references to a 32 oz can, then 30 oz, now 29 oz. The 16 oz can is now 15 oz.
That discount store sometimes deals with discontinued products, so maybe the 30 oz can is one of them with the 29 oz can the new standard.
To be really, really sure this wasn't a figment of my imagination, I pulled out my mom's old cookbooks.
It seems that most pies use the small can. Betty Crocker's Cookbook (1986) a while not mentioning brands, specifically says 1 can (16 oz) pumpkin. Since the recipe includes all the spices to add, they were not talking about pumpkin pie mix in a can.
Her Campbells Great American Cookbook (1984) just says 2 cups which is 16 oz.
This isn't a problem if making pie directly off the can because I'm sure it has been adjusted for the size change.
However, if you are hanging onto an old recipe that says 1 can of pumpkin ... and that recipe just doesn't seem the same ... well, that might be the answer.
For me, it just means in the future that I'll include cup measurements in notes with recipes I jot down or cut out ... 1 can pumpkin (2 cup cups).
Seems like the size of the evaporated milk can hasn't changed ... yet. It was 12 oz in 1984 and is 12 oz today.
Just a thought for anyone baking pies for turkey day.
