Pour water and half a glass of juice into a saucepan. I use juice drained from canned cherries, I have it sweet and sour. Bring to a boil. Pour in the semolina. Reduce heat to low. Cook for 20 minutes, stirring so that the porridge does not burn. (Better to use a divider or a heavy-bottomed saucepan.)
Add sugar, mix. Bring it to a boil again and turn it off. The amount of sugar depends on the acidity of the juice. We cool the porridge to a warm state, it should not freeze and take in a piece.
Pour the porridge into a bowl and add the juice chilled in the refrigerator. This serving will take 1-1.5 cups of juice, depending on your taste. Beat for about 10 minutes. If the mixer overheats, you can take a break. The taste of the mousse can be adjusted. If you want to sweeten it, add the powdered sugar while whisking. If sour, add more juice or a little citric acid.
This is what the finished semolina cherry mousse looks like. We lay it out in portioned vases, glasses, or glasses. Cool the cherry mousse in the refrigerator.
