Lemon Curd Tart (with a buttery biscuit base)

Ingredients: 

Lemon Curd:

• 110g butter


• Zest of three medium lemons


• 150g caster sugar


• 3 eggs


• 175ml freshly-squeezed lemon juice

Base:

One quantity of the legendary Buttery Biscuit Base

We ate it before we could take a photo!

Instructions: 

• If you have a good, reliable, heavy-bottomed pan then you can simply dice the butter and pop in the pan with all the other ingredients.


• Otherwise, use a glass bowl over a pan of boiling water.


• Mix continually until even, then intermittently until the mixture thickens and the first bubbles appear.


• Remove from heat and allow to cool a little before spreading on the biscuit base.


• Refrigerate at least an hour.
