Dry in oven 6 to 12 hours or until tomatoes are shriveled, dry to the touch and very chewy in texture, turning once after 4 hours. Edges may be crisp, but tomatoes should not be crisp in center; they should be somewhat pliable. Check after 6 hours and remove any smaller tomatoes that have dried. Tomatoes will be dark red and some pieces may have brown or dark spots.
