I wasn't in the mood to stand at the stove all day since it was so glorious outside, and when I was washing up the dishes (yes, from last night) I looked at the slow cooker and wondered... "can you make marmalade (or jam) in a slow cooker?"
It turns out the answer is yes!
Here's what I did...
I had made some straight Pomello marmalade when the Pomellos first arrived at home. I googled it and found a "boil and blend" recipe that sounded different and a bit more interesting than others. It worked really well and so I decided to use that recipe but use the slow cooker instead of the stove to do the actual cooking - that way I could multi task, make marmalade and do some gardening both at the same time!
Then cut the pomello/orange/lemon/lime into segments leaving out the tough membrane in between. This bit doesn't break down blend in well, so its best not to have in there then you wont have to fish it all out later!
Pop all the skins into a pot of water and boil them for about 5 minutes. Then empty the water out and do it again, And then again. Three times is usually enough to take out a lot of the bitterness in the skins. Then either cut the skins into skinny slices... or pop them in the blender!
Put all the fruit pulp that you painstakingly cut out of the membrane into the blender and then add the skins and hit the high button!
Green-ness: 5/5 for using fruit that was in season and falling off the trees!
Frugal-ness: 5/5 for getting six jars of almost free marmalade ( I had to pay for the sugar!)
Time cost: About 5 hours - but there's at least four hours worth of gardening in there as well!
Skill level: pretty basic cooking and cutting skills!
Fun-ness: Great fun to have marmalade and be able to play in the garden!
