Transfer it to a small saucepan with a heavy bottom.
Passionfruit pulp: This recipe was made using unsweetened passion fruit pulp. If you use sweetened passion fruit juice for this recipe, make sure to omit some of the sugar so the curd is not overly sweet. I'd say reduce it to about half, but it will depend on how sweet the juice you are using is. You can find passion fruit pulp at some grocery stores, sometimes it can be found in the frozen aisle. I always get mine on Amazon. This is the Passionfruit pulp I buy. And these are the Passion Fruit Seeds with Pulp I recommend if you want to decorate your pie with the seeds but can't find any fresh passionfruit.
White chocolate: Make sure to use real white chocolate, as I indicate in the recipe above. These is my favorite white chocolate: Callebaut White Chocolate Callets. If you can't find real white chocolate chips at your store (which should contain at least 20% cocoa butter) you should buy the white chocolate bars and chop it to use in this recipe. The store brands white chocolate chips (not real white chocolate) will not work in the recipe.
Chocolate crust: Feel free to use any crust you would like, a pre-made crust, a regular pie crust, or tart crust. If you want to, I suggest serving it with my delicious Chocolate Tart Dough, it cuts right through the tangy and sweet passionfruit filling, and brings the whole experience to the next level!
