2 lb fruits
1 lb sugar
Boil fruit with ½ cup water for about 10-15 minutes, then puree using a blender.
Boil the puree with low heating (avoid burning!) stirring sometimes and adding sugar by tablespoons.
After that, stir all the time until the mix stops sticking.
Cover a large flat dish with wax paper and lightly grease with butter. Spread the marmalade evenly on top. Allow to dry and cut.
