Servings: 4 people
Prep Time5 mins
Cook Time10 mins
Total Time15 mins


  • 1.25 cups Heavy / Double Cream - (300ml)
  • 1/3 cup Caster Sugar - (75g)
  • 1 Lemon - juiced


  • Put the all the ingredients into into a large saucepan, bring to the boil and simmer whilst stirring for 3 minutes.  Its best to use a spatula so you can keep scraping the sides and bottom of the pan.
  • Allow to cool so you can comfortably touch the side of the pan.  
  • Pour the mixture into individual dishes (ramekins, wine glasses, espresso cups - it is very rich so a smaller serving is better) and chill in the fridge for at least 3 hours. 
  • Serve with a slice of lemon and a little cream poured on top


  • When zesting and juicing lemons always zest before juicing
  • To extract the most juice roll the lemon on the kitchen worktop with a moderate pressure under the heel of your hand.  If you want to you can add the zest for extra flavour, but I think that it spoils the silky smoothness of the posset.
  • When heating the mixture watch the pan all the time. Like milk, boiling cream will erupt in the pan like a volcano and the second you take your eye off it, it will boil over.  If you need to answer the phone, or door take the saucepan off the heat.
  • Stir the mixture constantly when cooking.  It will thicken first on the sides and bottom of the pan, I like to use a silicon spatula to constantly scrape the sides and bottom of the pan.
  • Once cooked wait a little while before transferring to serving dishes so there is not risk of the boiling hot cream cracking them.  I like to use vintage glasses which easily crack with a change in temperature.
  • To avoid dribbles down the side of the serving glasses use a jug to pour the warm cream in, or a jam funnel.
  • Any splashes of cream or smears can easily be cleaned up with a cotton bud dipped in vodka.
  • Lemon possets will freeze well.  Just pour a little liquid cream over to hide any cracks which appear!
