Slice the 8 passionfruit and use a spoon to scrape the pulp and seeds into a bowl. This should yield around 150 ml with the seeds. Then press the passionfruit pulp through a fine sieve into a bowl using the back of the spoon, to remove the seeds. This should yield around 100 ml passionfruit juice.
8 passionfruit
Prepare the rest of the ingredients - weigh out the sugar and butter and get the eggs ready.
150 g caster sugar (superfine sugar), 50 g butter, 2 medium free-range eggs
Add the eggs, sugar, butter to the juice in a large bowl (ceramic or glass for example, that can be used in the microwave).
Mix using a fork (make sure you beat well so that the eggs are fully combined). Microwave on high for one minute, then beat again with the fork.
Microwave on high for 2 minutes. Stir well after heating to remove any lumps. You'll see the curd start to thicken up.
Microwave on high for another minute then stir well. You should now see that the texture of the curd has changed (much thicker) and it has a shiny surfaceCheck if the curd is coating the back of a spoon - dip a spoon into the curd and seeing if it slides off or remains on the back of the spoon. If it coats the spoon then the curd can now be put in the fridge to set, after sieving.Note - if it doesn't coat the spoon yet, heat for another minute, stir then check again. Sieve the curd once more to remove any white stringy bits from uneven heating.
Pour the curd into a sterilised glass jar, put on the lid, and allow to cool fully. Then refrigerate.
