Passion Fruit (Granadilla) Slice

You know that playground chant, “my dad’s bigger than your dad!”, “well, my dad’s stronger than your dad!”, “well, my dad’s faster than your dad”… until blows come or the bell rings? That’s how I feel about passion fruit. Where I grew up in South Africa we didn’t have passion fruit, but granadilla, which is family of passion fruit, but, you know… bigger. So there. My granadilla is bigger than your passion fruit!Passion Fruit Slice

I did always love granadilla, but it wasn’t always a common thing to find in the UK – even as passion fruit. Recently that’s changed, and I seem to see passion fruit everywhere. And when I found them on sale in Waitrose yesterday, I had to grab a couple to make a tray bake that combines two ingredients I always view as truly South African: this gorgeous seeded fruit, and condensed milk. (So many South African deserts use condensed milk!)  A little bit gooey cake and a little bit pudding, this combines the tropical flavours of passion fruit and coconut into one delicious, ridiculously sweet snack.

As always, I use this fab brownie pan with the removable base. It’s the perfect size and works well.

You can use a few tablespoons of pulp from a jar, if that’s what you have, but fresh works just as well for a hint of tart among the sweet. Hope you like it!
