Lemon Curd

(Made with our massive lemons, probably about three standard lemons worth each)

• Zest of 6
• Juice of 2 (160ml) 
• 1/4 tsp salt 
• 1 1/3 cup sugar 
• 8 egg yolks
• 2 tbs cornflour

plus 165g butter

Mucked around with double burners and thickening for ages, in the end chucked in cornflour and did it in the microwave, Bob's your uncle. Cook the main ingredients with some caution until thickish, then stir the butter into the hot stuff. Done.
