What's purple and yellow inside?

Well, at one point, it was the purple heirloom carrots. For this post it's Italian plums (or prunes) from Rutger's Garden Farmers Market.

Yellowish green on the inside

Got these last year and made a batch of jam that so sweet and delicious. They are great for eating but the jam is great and easy. I make small batches about 2.5–3lbs a batch, about 2 pints. And I don't add anything special with these just the fruit and the sugar. That's all it needs. 

Here's what it looks like cooking down.

It really turns this beautiful plum-y color.
