Shiro, Kuro, Chairo...Whatro?

I've been having an interesting time discovering new fruits and veggies from my CSA (community supported agriculture) that I joined this year. While some of the oddball veggies has been a challenge to cook, the fruits have been a fun exploration. This week, I got some Shiro (white) Plums which are a Japanese variety of yellow plums. And so, I return to lessons from food! As it turns out, these shiro plums from Windy Brow farms are delicious! They are incredibly dribbly-all-over-your-hands juicy with a wonderful floral scent in the mouth on top of the "typical" plum flavor. However, they have a pale yellow skin and flesh...so why call it white? I'm thinking its the flowers...
