Passion Fruit Curd done in the microwave!

Several years ago I posted how to make lemon curd in your microwave. Here is a variation I made - passion fruit curd.

You can find the passion fruit puree in larger Whole Foods freezer sections. (Arden one does not carry.)
Passion Fruit Curd

1 cup white sugar
3 eggs
1 cup passion fruit puree
1/2 cup unsalted butter, melted

In a microwave-safe bowl, whisk together the sugar and eggs until smooth. Stir in puree and butter. Cook in the microwave for one minute intervals, stirring after each minute until the mixture is thick enough to coat the back of a metal spoon. Remove from the microwave, and pour into small sterile jars. Store for up to three weeks in the refrigerator.
Tip: If you over cook the mixture a little, or forget to stir, you can pass the mixture through a fine sieve to remove the bits of cooked egg.
