I ended up in Sedona right after the big festival last year and saw a cookbook I had to have, by Bruce Horowitz. Suffice to say that I thought I was familiar with the majority of ingredients and techniques!
He has a recipe for sprouted rye bagels that I really want to make, but in the process it says to put the mixture through a juicer with the blank plate in. What does this do to the ingredients, and can I substitute some other process?
Basically, it grinds and homogenizes the ingredients (sometimes it is referred to as a homogenizing plate). For most purposes, a food processor should work fine (I think!), just try to work slowly and pulse ingredients rather than just running it straight.
cannibalwarrior and jenny are correct. The ‘blank’ referred to is simply a blank piece of plastic instead of a screen, so the food is ground up very fine and ejected as juicy pulp instead of juice out of the spout and dry pulp elsewhere. Processing very well in a food processor will approximate this.
