I didn’t measure but it’s about 1kg berries to 6 cups of sugar and 1 1/2 teas citric acid. I use a non stick saucepan. Mash the strawberries with a fork, add the sugar and stir in thoroughly. Bring to the boil until the sugar is almost dissolved, add the Citric acid and boil until setting point (105 degrees) remove the skum from the top and pour into hot sterilized jars
