i just made orange marmalade/jelly using 450gr bitter oranges 3 pts water 3 lbs sugar and 3 tablespoon of lemon juice and it did'nt set any hints please
Reheat your mixture to boiling, mix 1 package pectin with 1/2 cup sugar and stir in… boil hard for at least two minutes, pour into prepared jars and seal.
Sounds like too much water -there should be enough liquid in the oranges without the need to add any extra. Boil it back up to evaporate some of the extra liquid.
