Home Cook Conserve - Prepared Strawberry 825g 4 "Make your own Strawberry Conserve/Jam" Mrs Federico 12 March 2013 Having read the reviews for the strawberry jam I was a little apprehensive. I used 1 kg of jam sugar and decided to add 8oz of hulled and chopped strawberries, the juice of 1 lemon and only 1/4 pint of water. I let it simmer for at least an hour and did regular wrinkle tests as I went. I found it was a little sharp, so added about 2/3oz of caster sugar. Once cooled in the jars, I let them set completely in the fridge. All I can say is, this is amazing jam!! Has just the right texture and has made 5 decent sized jars. I would suggest doing the above and you won't be disappointed!!!
