The passionfruit vines in my backyard have dropped a huge amount of fruit, and I need to do something with it. When it comes to preserving acidic fruits like passionfruit, marmalade-style preserves are far and away my favorite. Most of the recipes I located online were for passionfruit curd or some passionfruit gelatin concoction, but after a little digging, I finally discovered this perfect recipe from The Cook's Cottage. I'll make it this weekend and report back.
Update: I strongly recommend the recipe. It gels beautifully, it's very tasty, and it will make your house smell wonderful.
