Identifying Ingredient P.P.M.

Toast

Hey all!

I just found an old restaurant’s recipe binder at a thrift store, and I found a recipe for Ciabatta. One of the ingredients is labeled P.P.M. Any idea what it could be?
I’ve researched a lot on this site and others but can only find references to “parts per million” for additives. If it’s any help, the P.P.M. has a bakers percentage of about 2%.

 

thanks! 

So we can see what's been including and deduce what seems to be missing which may be the P.P.M. referenced.

The only reference to P.P.M. I can find is Parts Per Million but that wouldn't explain the 2%. 

P.P.M. is a term used when using ascorbic acid. It could very well be that earlier on in the recipe binder it explains how to measure it out in a liquid suspension and the 2% in the recipe is how much of that suspension to use.
