Grind in a meat grinder. I have an electric meat grinder - everything ground very easily and quickly, but you can do anything. You can also use a juicer, then after pressing, mix the juice and the "cake" (dry part). Can be ground with a blender if the volumes are small.
Add sugar to the mixture of juice and cake. The proportions may vary. The average proportion is 1: 1. But you can use a lesser quantity of sugar.
Add pectin (again, you can follow the instructions on the bag, or you can add less - the plums have their own pectin). Boil and stir for about half an hour.
We leave the mass. We prepare the surface on which we will dry the marshmallow. It can be a foil or thick oilcloth - for natural drying in the fresh air. You can also oven-dry the pastille. When the mass has cooled down a little, carefully distribute it over the surface. I decided to make the pastille thicker - the layer of mass was about 1 cm. Dry the marshmallow from the plums until tender. Pastila is considered ready when it can be removed and rolled up. My plum marshmallow remained a little sticky, although it dried for 3 weeks in the attic. But the plum marshmallow turned out to be softer than the previous one, apricot.
We detach the pastila from the surface on which it was dried, roll it up, and cut it. I like the thinner marshmallow rolls - they are more convenient, in size, like candy.
It is very tasty to eat marshmallows with nuts! So delicious that I will most likely fold the next one, sprinkling with crushed almonds or walnuts. But a bite is also possible.

Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
