While the tubes cool, make the cream. To do this, pour water into a small bucket and add the necessary amount of sugar. Put on a heat and bring everything to a boil. Add a pinch of citric acid to the boiled syrup and continue cooking to 120 degrees. If you don't have a kitchen thermometer, then drop a drop of sugar syrup into cold water. If a ball can be rolled from this drop, then the syrup is ready. If not, then cook more.
