Greengage Jam with Chartreuse

We currently have twenty flavours of jam we make for Sticky Spoon, but we can't help but play around with different fruits and spices at home as a way to come up with new flavour ideas for the following seasons. A few weeks ago, while discussing different types of plums with the kind gentleman who co- owns Klippers Farm, I started thinking about Greengage plums and how their dessert-like, sweet, delicate nature would pair nicely with a hint of green Chartreuse. There was only one way to find out... 

As it turns out, the combination makes for a bright and fresh jam, a great breakfast companion to Greek yogurt or even mild goat or ricotta cheeses. We are pleased with the results and add this flavour to the potential new jams for 2013. What do you think of Greengage Jam with Chartreuse? Would you add a jar to your pantry?
