Tomatoes: squeeze the juice and seeds from a ripe tomato into a small jar
and add a little water to dilute it. Sit it aside somewhere that your
family won't find it and throw it away. Let it rot for a few days. Then
filter out the seeds and rinse them and dry on a paper towel.

The only things I would add to this are to wait until there is a
slight smell of fermentation and a small area of white appears at
the surface. Dead seed float and live seeds sink. The seeds
might appear slightly grey.

Wash them off and let the good seeds dry on a coffee filter or
paper towel.

The seeds should be good for several years. The fermentation
kills a lot of diseases.

If rubbing the seeds together between your fingers pulverizes
them then you have overdone the fermentation.
