Mirabelle Plum Jam
Mirabelle plums not only taste great, they are also healthy: 100 grams contain 20 milligrams of panthothenic acid. The substance is also known as vitamin B5, which is not only essential for energy production, but also for growth, the nervous system, wound healing and hair pigmentation.
If you work cleanly, the sweet spread will keep for several months. Once opened, it should be used up in the refrigerator and consumed soon.
Remove pits from plums and combine with lemon juice and 50 ml (approximately 1/4 cup) water in a pot. Cook until softened, 3-5 minutes. Strain through a sieve into another pot and let cool. Stir in apple juice and lemon zest to taste. Add jam sugar and let stand at least 1 hour.
Slowly bring mixture to a boil, stirring constantly. Boil mixture until set, about 4 minutes. Add citric acid if needed and cook 3-4 minutes more. Pour jam into sterilized jars, up to brims. Seal and tap firmly. Invert jars for 10 minutes, then stand right-side up and let cool.
