Thanks to all about prepping the seeds. I should have stated my question a little more clearly.
I'm planning on growing out several plants of the Romeo roma that used to be offered by Peters Seed & Research, and making a lot of sauce for my household. If the seeds left over from processing the tomatoes are not damaged from a food mill, then I'll have a lot more seeds to save and share...
.
I'm hoping to get feedback from some folks who have previously done this, and can recommend a food mill/processor that has worked for them. In particular, for seed saving purposes, I'd like a machine that could either handle raw tomatoes, or tomatoes that have only been dipped in boiling water for a few seconds to soften the skins.
In addition to Feldon's and Tatiana's procedures for prepping the seeds, I have Carolyn's book as well as
Seed to Seed for references, so I have lots of options there...
Thanks again to everyone who has replied so far.
