This is an attempt to recreate an old recipe used by my girlfriend's grandmother for green tomato preserves. The recipe could not be obtained from said grandmother because she simply cooks everything until it "looks right". We based our recipe on whatever my girlfriend could remember from her childhood and some other sources around the internet.
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
Unfortunately, we didn't start taking photos until after we had chopped the tomatoes and lemons, so photos from that step are missing.
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
Add the sugar to the tomatoes and lemons and stir until the sugar dissolves. Let this sit for a few hours.
Step 3: Boil!
Boil the tomato-lemon mixture for a while (it took us 3 hours). You're looking for the tomato chunks and lemon rinds to completely break down. The liquid should become very dark green. Stir the mixture frequently to prevent any burning.
