The best lemon curd recipe is zesty and tart, sweet but not too sweet.  This fruit curd recipe is exactly that.

This easy recipe uses 4 simple ingredients. Eggs (whole eggs and yolks), fresh lemons (fresh lemon juice and zest), white sugar, and butter.

Mix all the ingredients except the butter into a heat-proof or glass bowl.

Set up a water bath by filling a saucepan with about 2 inches (4cm) of water and bringing it to a simmer.

Whisk it together over the simmering water for around 12-15 minutes until it starts to thicken.

Then take it off the heat and whisk in the cold butter.

Pour the curd mixture through a fine-mesh sieve, into a clean jar.
