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.
