Hi there, i need help with the lemon possets im making lately. They've stopped setting for me and are very runny! When i made them in the beginning they were perfect! I loved making them and they were so easy. Now they're a nightmare! I didnt change anything in the recipe or do anything differently. This is the recipe and method i use 600ml cream, 150g caster sugar, 4 lemons juice and zest I bring my cream to a boil with my sugar and let it cool slightly then add lemon juice and zest and stir well. I sieve it and put it into glasses. When that stopped working i tried adding the juice and zest while its on the heat and it didnt work either. Ive noticed the lemons are not very sour and i could eat them without my face scrunching up! I added citric acid to the mix then but still nothing! These methods didnt help with setting. So I have no idea what could be happening and if anyone could help me id be so happy! Thank you!
