Step-by-Step Guide

Step 1: Decide whether or not to use pectin.
You don't have to use pectin to make jam; however, it will help the jam have a jelly-like consistency and can keep it from being runny.
You can find it in most supermarkets, in the canning or baking aisles, and it can be bought as a liquid or a powder.
However, if you do use pectin, then you should read the instructions for the exact sugar-to-fruit ratio of ingredients you should use.
This will make the recipe vary slightly. -
Step 2: Sterilize a dozen canning jars.
You can't use any old jars
-- you'll need to get jars that are specifically meant for canning.
To do this, boil the jars in water for 10 minutes.
Then, place them upside-down on a clean towel and drape another towel over them until you are ready to use them.
You may not need all 12 jars, especially if you are using larger jars, like pints, but it is much easier to prepare too many than too few.
It's crucial that you sterilize the jars correctly because the basic principle of canning is to kill all the microorganisms that spoil food, then to seal the jar tight to keep them out. , First, wash the fruit under running water and then do whatever you have to do to get it to be ready to eat.
Peel it, remove the pits, the stems, or whatever else you need to remove.
Then, cut the fruit into small manageable chunks.
If you're using raspberries or blueberries, you don't need to cut them, but if you're using apricots or strawberries or other fruit larger than berries, then you should cut them into 1 , Once you've washed and prepared the fruit and have given it a little bit of time to dry, then you should crush the fruit with a potato masher or a wooden spoon.
You don't have to go crazy with this
-- the fruit will naturally soften and will become more malleable as you boil it.
How long you spend crushing the fruit depends on what kind of jam you'd like
-- if you'd like thicker jam with larger chunks of fruit, crush the fruit for 1-2 minutes; for smoother jam, go for 3 minutes. , First, place the 8 cups of fruit in the pot or pan, and then add the lemon juice and butter to the mixture.
Add 1/4 cup of lemon juice and 1/2 teaspoon of butter and margarine.
Gently stir in the ingredients.
You can warm the butter up to make it easier to stir in.
The lemon juice will cut some of the sweetness of the jam. , A full, rolling boil is one where the bubbles do not stop or lessen when you stir it.
Stir constantly and all the way to the bottom to avoid burning the fruit.
Boiling the fruit mixture will make the juice come out of the fruit and will keep the pot from burning. , Pour in the sugar, with the heat still on, and stir it in until it dissolves completely.
You will notice that the fruit becomes clearer and brighter when you add the sugar.
Continue stirring constantly.
For this recipe, you should use 4 cups of sugar for 8 cups of fruit a (1:2 sugar to fruit ratio), but know that ratios can vary.
If you're using a more bitter fruit, like orange, then the ratio should be more like 2:3 (two cups sugar for every three cups fruit).
Don't skimp out on the sugar.
You may think that this will make the jam healthier, but it will actually ruin the consistency of the jam. , Heat the mixture under low heat until it reaches the right consistency; the time this takes varies by the type of fruit you're using, since some fruit takes longer to soften.
If you're using pectin, check out the time required for boiling on the package.
Continue stirring constantly.
You can test the consistency of the jelly with a chilled spoon. , When the mixture is ready, turn off the heat and remove the pot from the burner. , It will be whitish, and some batches will have more than others.
You don't have to get every speck, but if you leave it in the jam, it will change the consistency and not taste very good. , Use a canning funnel to guide the jam into the jar.
Make sure to leave 1 , Boil about an inch of water in the bottom of a medium saucepan and remove it from the heat.
Place the seals into the water.
Push them down so that they sink, and try not to stack them on each other, so that they heat evenly.
Allow them to soften for a minute or two.
You can do this step while you ladle and wipe rims, if you time it right.
Place a softened seal on each jar.
A magnetic lid wand will help you get them safely out of the boiling water.
To release the seal, set it on a jar and tilt the wand.
If you don't have a lid wand, you can use a small pair of tongs.
Screw a clean ring down over the seal and tighten it with snug hand pressure.
Don't tighten so much that you press all the seal material off of the rim. , To do this, lower the jars onto a rack in a water-bath canner or large stock pot.
If you use a large stock pot, place a rack or other spacer on the bottom so that the jars do not rest directly on the bottom of the pot.
Add enough hot water to cover them by 1-2 inches.
You can measure it to the first knuckle, as shown.
Then, cover the canner and bring the water to a gentle boil. , Remove the jars from the boiling water.
Jar tongs are a secure and safe way to do this, or you may be able to raise the entire rack in a water-bath canner.
Place the jars on a clean towel to cool.
Allow the full jars to cool for 24 hours in a place free from drafts.
You may hear the metal lids make a loud plinking sound.
That is simply the contents cooling and creating a partial vacuum in the jar. , The vacuum created when the contents cooled should have pulled the "dome" lid down very tightly.
If you can press the center of the lid down, it did not seal.
It should not spring back.
If any jars have not sealed, you can place a fresh lid on them and process them again or refrigerate those jars and use the contents soon.
Wash the jars in cool, soapy water to remove any sticky residue on the outsides.
You can remove the rings at this point, since the seals should be holding themselves on securely.
Allow the rings and jars to dry thoroughly before replacing the rings, to prevent rust. -
