Strawberry Jam

Recipe

1 kg washed, hulled and cut in half STRAWBERRIES
350 - 400 g SUGAR
1/3 cup LEMON JUICE
 
Put strawberries in a pot. I used my Le Creuset pot. Let them boil for 40 min ( until it thickens) steering often.  Remove foam.
In a meantime fill canning or any stainless steel pot with water. Insert metal rack ( mine was too big so I used ) Put washed jars in the pot ( make sure that water covers them about an inch (2,5 cm). Simmer until jam is ready. In a small pan, in hot water heat jar lids.
How to check if jam is done : put little jam on a plate, cool and if it doesn't run its done.
Carefully take jars from water using jar lifter. Fill jars leaving space about 1,5 cm from top. Stir with plastic bubble remover and clean around the rim. With lid lifter take the lid and put it on a jar. Screw the top but not too tight. Slowly put all the jars back in the water. Bring to boil and  than count  10 min. After 10 min take them out on the  kitchen towel. Don't tilt. You will hear popping sound. Leave them to rest for 24 hours and check that lids are sealed. Store in cool and dry place for up to a year.
