24 large green tomatoes
3 red bell peppers, halved
   and seeded
3 green bell peppers, halved
   and seeded
12 large onions
3 tablespoons celery seed
3 tablespoons mustard seed
1 tablespoon salt
5 cups white sugar
2 cups cider vinegar


Directions
1 In a grinder or food processor, coarsely grind
   tomatoes, red bell peppers, green bell peppers, and onions. (You
   may need to do this in batches.) Line a large colander
   with cheesecloth, place in sink or in a large bowl, and
   pour in tomato mixture to drain for 1 hour.
2 In a large, non-aluminum stockpot, combine tomato
   mixture, celery seed, mustard seed, salt, sugar, and vinegar.
   Bring to a boil and simmer over low heat 5 minutes, stirring frequently.
3 Sterilize enough jars and lids to hold relish (12
   one-pint jars, or 6 one-quart jars). Pack relish into
   sterilized jars, making sure there are no spaces or air pockets.
   Fill jars all the way to top. Screw on lids.
4 Place a rack in the bottom of a large stockpot and fill
   halfway with boiling water. Carefully lower jars into pot
   using a holder. Leave a 2 inch space between jars. Pour in
   more boiling water if necessary, until tops of jars are
   covered by 2 inches of water. Bring water to a full boil, then
   cover and process for 30 minutes.
5 Remove jars from pot and place on cloth-covered or wood
   surface, several inches apart, until cool. Once cool, press top
   of each lid with finger, ensuring that seal is tight and (lid does not move up or down at all). Relish can be stored for
   up to a year.
