Due to the fact that I did not remove the pulp from the films, the puree turned out to be heterogeneous. If you like a more uniform consistency, squeeze the juice from the tangerines and continue cooking according to the recipe.
Put the tangerine puree in a saucepan.
Mix the pectin with 1 tablespoon of sugar, add the rest of the sugar to the puree.
Bring everything to a boil, and then “rain” pour in the mixture of pectin and sugar, actively stirring the puree.
