This is a preserve that most people (including myself before today) don't know much about. Even the guy we bought the tomatoes from asked "You can make preserves from those?"
Step 1: Collect and chop ingredients
Here are the ingredients we came up with:
8.5 lbs green tomatoes
5 lbs sugar
To prepare the tomatoes, remove the stem and chop them into reasonable sized chunks, maybe 8-12 pieces per tomato depending on the size.
To prepare the lemons, slice into wedges and remove the seeds. Do not remove the peel (it's the best part!) Chop the lemons into 1/2 long strips.
To prepare the sugar, open the bag.
Don't forget the to pick up some cans. We went with a dozen pint jars which ended up being more than enough.
Step 2: Add sugar
Step 3: Boil!
Step 4: Can
1. Clean the jars and working utensils thoroughly by boiling them for several minutes. Instructions on the box said to keep the jars in 180 degree water until you were ready to use them, but since we were running out of stove top space I put the cleaned jars in a 180 degree oven.
2. Put the jar lids in hot (not boiling) water. I kept it at about 180 degrees. If you boil the lids you will melt the sealing compound off the rim.
3. Fill the jars with preserves up to about 1/4 inch below the rim. Clean any spilled preserves from the rim or sides of the jar. Place a lid on top and screw on a ring until just finger tight. It's a good idea to have several towels or hot pads ready for this step, as every item you're working with is very hot.
4. Process the jars in boiling water for 10 minutes. Process is just the fancy canning word for putting the jars in several inches of boiling water.
