Pour a jar of condensed milk into a high container. Then the same amount of cream (an empty condensed milk jar, here - a measuring jar). Beat.
Then squeeze the juice of 1 lemon into a separate cup. Add to the mixture and whisk well. Try it on acid. Add the juice of the second lemon. Try. I added the juice of 3 lemons, but it's up to you. And lemons are of different acidity everywhere.
The cream thickens quickly, but in order to reach the condition, it is recommended to put it in the refrigerator.
