grapefruit and vanilla curd

Summer wouldn’t be summer without tea in the garden. Think cucumber sandwiches, home-baked biscuits, a Victoria sponge oozing strawberry jam and, of course, feather-light scones. As a change from the usual lemon curd, try this grapefruit version.

Ruby Grapefruit and Vanilla Curd


  • Zest and juice of 1 ruby grapefruit
  • 100g caster sugar
  • 1 whole egg and 1 egg yolk
  • 1 vanilla pod, seeds scraped out (keep the pod to flavour sugar or vodka)
  • 1 heaped tsp cornflour
  • 50g butter, cut into pieces


In a pan over a low heat, whisk together the grapefruit zest and juice, sugar, egg and vanilla. Keep whisking as the mixture heats – be patient and resist the urge to turn up the heat or you will end up with grapefruit-flavoured scrambled egg! Once the mixture begins to increase in volume, add the cornflour. Keep whisking until it is pale in colour and very thick, then beat in the cold butter and bottle in sterilised Cubo jars. Refrigerated, the curd will keep for a couple of weeks.
