The frost has hit here in the pacific northwest. I picked all the tomatoes off the plant and I'm wondering if there is any way to ripen them. Right now I've got them on a tray pan and place them in the sun each day, and take them in at night. Is there a better way or any way to ripen these tomatoes?
