It's not as much jam as jam, but almost without work in a home bakery. Cut a lot of ripe strawberries into smaller pieces and put in a baking dish. I have a smaller bakery (per 1 kg), so I give 1 kg of strawberries + 1 Gelfix + 300 - 400 g of sugar and I turn on the bakery for the "jam" program. It is possible to add 1 - 2 teaspoons of citric acid, but only in the end. Before the jam is cooked, I'll boil a glass in a casserole, so then fill straight into the hot ones. To close, turn upside down for about 10 minutes until the lids close. There are about 4 glasses of 300 ml. I make apricot jam in the same way and I plan another one ...
