Cooking is fun, especially when recipes take only moments to make, yet produce a stunning dish. the ultimate lemon posset is one such recipe. 

Originally a posset was a drink made from hot milk and honey, spiced and laced with ale or wine. It was popular in the Middle Ages as a remedy for colds and minor ailments and a sleep-aid. Posset appeared in Shakespeare's Macbeth when Lady Macbeth used a poisoned posset to knock out the guards outside Duncan's quarters. Later it became a thickened cream dessert, usually flavored with honey and lemon but do check out the alternatives to the traditional posset below.

  4. Bring the cream to a gentle boil. A heavy boil will spoil the cream and ruin the recipe.

Traditionally a posset is served with slivers of toasted almonds, but is also delicious with summer berries and Scottish Shortbread.

Recipe Variations

  • Lemon may well be the traditional posset, or at least the one we know nowadays. It is, however, lovely to ring the changes.
  • Change the citrus flavor by using lime juice instead.
  • Mix different citrus flavors - Lemon and clementine juice are wonderful.
  • Add a little vanilla extract to the cream and syrup mix. Be sparing though; vanilla can overpower and spoil the delicate lemon flavor.
  • In medieval times a posset would have honey, as well as spices, which though expensive at the time, were also much-loved flavors. Try a light grating of nutmeg (keep it very light). A pinch of ground ginger and for an autumnal feel, try a tiny pinch of mixed spice (known as Pumpkin Spice mix in the US.)
  • Add a little alcohol. A dash of sweet wine, Madeira, or for an authentic flavor - mead. Add the alcohol when whisking the syrup into the cream.
