after the tomatoes boiled for @ 10 minutes the skin started to crack and lift off. that is when you know they are ready to peel.
here are the peeled tomatoes. to speed up the process of cooling them i ran cold water over them and added some ice to the stock pot.
i cut them lengthwise to remove the seeds.
here is the onion and jalapeno puree that i used to mix with the chopped tomatoes. all vegetables for the pico were chopped in the food processor.
