Didn't want to take away from the "what have you ..." thread. With AK harvesting tomatos by the basket full, i thought it would be good to share this little tip. My stepdad shared this with me and I used it with this harvest and it is effective.

Cut open a tomato and scrape out the seeds, which will have pulp and a jell type substance with them. Put all this in a glass jar, pint mason jar works well. Fill it maybe 2/3rds full of water and set it in a non sunny location. Swirl the water around a couple times a day. After two days, drain the water and rinse the seed thru a pretty tight sieve, then put the seed back in the jar and refill with water. Repeat the swirling for the next 3-5 days, then drain and rinse very well. The seed should be pretty clean and ready to spread out to dry.

During the soak and swirl cycles, the pulp and jell stuff will begin to seperate from the seed and you will see that in the water. Hope this helps someone.
