Watermelons in jars for winter with mustard

1. Rinse the watermelon under water and wipe it dry. Watermelon is better to take medium ripeness, whole without cracks. We cut it into slices, which will be convenient to put in jars. After the whole watermelon cut into pieces has been laid out, pour boiling water from the kettle into the jars. Cover with lids and leave for a while, somewhere for 5-7 minutes.

2. Drain the liquid from the cans into a container, and we will cook the marinade. Pour out the salt and sugar, stir and bring to a boil.
3. Put mustard and citric acid in jars, carefully pour the watermelon slices with boiling brine. We roll up the lids, turn them over and let the jars cool down in a warm place, under a blanket. After that, we put it away for storage in a cool place.
