This week: Passion Fruit Sponge Custard.  Not the most elegant dessert we’ve ever made, but ignore the appearance, go for the taste, like the fruit itself.  Ripe passion fruit resemble hard-boiled eggs, after the apocalypse, wrinkly red-brown ovals.  But inside, oh…  a pucker-sweet crazy delicious psychedelic orange pulp dotted with black seeds.  (You eat that goop?!  I thought nature made things in bright colors as a warning – poison! poison! poison!?  Nope.  Nature wants you to eat that goop, to, uh, carry the seeds away.)  The flavor of passion fruit hovers somewhere between orange and mango, just as sweet, but way tarter than either.  The only exotic fruit with an equal effort/pleasure ratio, IMO, is the durian, but we’ll reserve durian for another day.  In the meantime, try this sponge custard, an antique English dessert that’s not really spongy or a custard, flavored with an intense sweet-sour taste of the tropics.
