quilting here... yes i add lemon juice to my tomatoes. what we do, is called 'open kettle method'. and no body recommends it any more. but it has been a life saver for me, this yr. my tomatoes just are coming in 3 qts full at a time. so i do 3 qts several times a week. adds up.
does anyone do anything besides tomatoes this way anymore? you can PM if you don't want to admit it on the board. tomatoes are the only thing i do that way, besides jam. BUT I WASH MY JARS IN BLEACH, RINSE, AND MICROWAVE THEM.
