Blackberry jam

difficulty: ✦✦✧

preparation time: 1 hour

ingredients

• 8 cups of blackberries
• 2 tablespoons of lemon juice
• 6-7 cups of granulated sugar

tools

• potato masher
• BIG cooking pot
• wooden spoon (youll want to keep this one for making jam...you'll see why)
• mixer
• 5-7 jam jars

preparation

1. clean your berries in water and dry them off on a tray with a paper towel.
2. add the berries and lemon juice to your cooking pot and put them on medium high heat. mash them with a potato masher until most of the berries have fully broken down and let simmer for a few minutes.
3. use a mixer to further break down the berries into a smooth mixture.
4. slowly add the sugar and stir to combine. simmer on low heat for a few minutes to fully dissolve the sugar.
5. turn up the heat to max and keep stirring continuously until the mixture comes to a full boil. mix for 1 more minute and then remove jam from the fire.
6. allow to cool for a bit and then pour the jam in jars.
7. if you're reusing old jam jars you can fill the jar to the top, seal it and turn the jar upside down for a few minutes. doing this should make the jar seal itself and make your jam shelf-stable. (afaik this only really works with the jar-lids that make a clicking sounds when you press on them, which allows them to suck vaccuum after sealing them. )
8. if the jars are properly sealed they can be stored for several years
