Ingredients

4 kg fresh strawberries
2 kg granulated sugar
2 teaspoons citric acid, not heaped!

Preparation procedure

1. We clean and thoroughly wash the strawberries. We do not add strawberries that are rotten to the jam. The amount of sugar can be adjusted according to the sweetness of the strawberries.
2. If they are not very sweet, add more sugar; if, on the contrary, they are very sweet, you can reduce the amount of sugar.
3. Prepare a saucepan or another container. Place the first layer of strawberries on the bottom, sprinkle with sugar, continue with a layer of strawberries, again sugar, strawberries and a final layer of sugar. Cover and let rest overnight.
4. Leave the strawberries in a pantry or cellar – in a cooler place – do not put them in the refrigerator.
5. The next morning stir the mixture and transfer it to the stovetop and slowly heat it over low heat. For a smoother jam, you can blend the strawberries; however, if you don't mind larger pieces of fruit, it's enough to just stir. Add the citric acid to the mixture.
6. You can cook the jam in smaller batches, or all at once – in smaller batches it's easier (always take about 5–6 ladlefuls and cook in a pan with higher sides).
7. Cook, stirring constantly, until the mixture begins to thicken. Test the consistency of the jam before finishing by placing a teaspoon of jam on a plate that you previously put in the freezer – on the cold plate the jam will cool immediately and you can see at once what its consistency is.
8. If it then seems sufficiently thick, take it off the heat; if, on the contrary, it's too thin, cook it a bit longer.
9. While still hot, spoon the jam into clean jars and seal tightly, sterilize at 90 degrees for 10 minutes. Then turn them lid-side down, wrap in a blanket and let cool.
