Homemade jam is something special! And the great thing is, it is not that difficult at all! The time-consuming part about it is the preparation of the huge amount of fruit you need, but the rest is done in a jiffy. Well... cleaning up the sticky kitchen afterwards is the other thing (I always make a huge mess in my kitchen when I cook marmelade). But still, it's totally worth it!
500g strawberries, chopped into pieces
250g preserving sugar
Put the berries into a pan, add half of the sugar and bring to boil. Let boil for about 2 minutes, then add the rest of the sugar. Let boil for another 2 minutes.
Test whether the jam has reached the desired consistency by putting a little drop of it onto a plate. If it's not flowing anymore it's fine. Otherwise cook a little longer.
Fill the boiling jam into preheated glasses and seal them. Then turn them upside down for about a minute (kills the fungus spores) and then turn around again and let cool.
You can also add herbs or spices to the jam shortly before you fill it into the jars. Peppermint or vanilla for instance go well with the strawberries.
