I have made jam quite a few times, but I have never made it without adding water. Well, I am a convert to this method - so easy and so tasty! But what about the water? When you add the sugar to the strawberries and leave it to sit a little while the sugar draws out the water contained in the strawberries - it's an awsome little process called osmosis (this is one of the only things I remember from year 12 biology). You can find the recipe and many others that centre on strawberries here.
A shot of all the water that has been drawn out of the berries.Just make sure that you use a 1:1 ratio of strawberries and sugar and add some lemon juice or fruit pectin (e.g. Jamsetta) and you are ready to go. The recipe below uses a kilo of sugar and a kilo of strawberries, but when I made it the other day I used 55og strawberries and 500g sugar. You can add less sugar, but sugar is needed for its preserving qualities. Using a 1:1 ratio will mean that this jam will store for at least a year (though I doubt it will last that long!).
STRAWBERRY JAM
1kg Strawberries, chopped into small pieces.
1kg Sugar
Juice of 2 lemons or a packet of fruit pectin
Put the strawberry pieces into a bowl together with sugar and fruit pectin/lemon juice.
Leave the bowl (covered with a towel) in a cool place til the next day (if you are strapped for time, 1 or 2 hours should be sufficient). Stir once in a while.
Boil mixture then simmer for 5 - 10 minutes. Stir frequently. When finished take off the foamy top layer of the mixture.
To test the jam to see if it will set, put a teaspoon of the hot mixture onto a cold plate, if it gels, the jam is ready.
Pour the hot strawberry jam in hot sterilized jars.* Make sure to fill it up to the top. Clean the jars with a damp towel. Close tightly. After 10 minutes turn around and place jars on the lid. Let cool down, turn around again and store.
This would probably make about 4 medium jars of jam. Sterilize 6 to be on the safe side!
*To sterilize jars: wash in hot soapy water; rinse, put in oven heated to 110C - 120C for at least 10min; after 10min turn the oven off but leave the jars in there to keep them hot until you are ready to fill them up.
