Peel and chop the kiwi fruit.
Place chopped kiwi in a small food processor, blitz until smooth.
In a small pot, whisk together egg yolks, large egg, and sugar until well combined. Add the kiwi pulp and the citric acid, whisk until well combined.
Cook over medium heat, whisking constantly, until mixture thickens. It should be able to coat the back of a spoon and retain a clear trail when a finger is dragged across the back of the spoon. Ideally, you want the mixture to reach 165F - I use an infrared surface thermometer for this.
Once mixture is thick / hot enough, transfer to a bowl. Add the pieces of butter, whisking until well incorporated.
Once all of the butter has melted in and been fully incorporated into the curd, tint green with food colouring, if desired (We added a little too much, hence the neon colour!)
Transfer kiwi curd to your storage container and chill for at least 1 hour before use.
This kiwi curd will last for 2 weeks in the fridge, or a few months in the freezer. (Thaw overnight in the fridge before use!)
