Ingredients

The following ingredients have 12 Servings
  • 100 g (3.5 oz) salted butter
  • 100 g (3.5 oz) white sugar
  • 200 ml (4/5 cup) lemon juice ((about 6 lemons))
  • zest of 2 lemons
  • 2 Tbsp cornflour ((cornstarch in the US))
  • 2 Tbsp cool water
  • 100 g (3.5 oz) condensed milk

Instruction

  • Place the butter, sugar, lemon juice and lemon zest (if using) in a small saucepan on medium heat and bring to a gentle simmer. Stir, as the butter is melting, to mix.
  • Let the mix simmer for 1 minute.
  • Mix the cornflour and water to a smooth paste, and very slowly drizzle this into the lemon and sugar mix, stirring constantly, until the mixture has thickened.
  • Take it off the heat and stir the condensed milk in. That's it.
  • Transfer to a sterilised jar, bring to room temperature, then store in the fridge for up to a week.
