This works if you are saving a few seeds.
Fermenting the tomatoes seeds are actually better because it kills disease and
removes the protective coat over the seeds.

Squeeze a tomato into a container. Let it sit and ferment 2-3 days. Remove
the scum a rinse the seeds. Dry seeds completely.

If you are intrested in saving seeds, there are two good books I recomend.
The first is Seed to Seed by Suzanne Ashworth and the second is Saving Seeds
by Marc Rogers. Both books are around 20 dollars apiece.

I have a great batch of tomatoes and I'd like to prepare some of the seeds
for planting in the future.

Is there anything I should do other than remove them from the fruit and set
them to dry?

Thanks....
