My grandmother makes her own strawberry jam. I can close my eyes and feel the taste... nothing like it! (add a teaspoon to your apple compot on shabbos or just spread on fresh bread, if you are a sweet addict like me.... just eat it with a spoon) you might want to cook this jam just for the smell while cooking...
1 kg strawberries
1 kg sugar
Wash the strawberries and clean, removing stem.
Squeeze the lemon over the strawberries.
Cook strawberries and sugar on a very low flame for a few hours until ready.
