Plums and Prunes

The other day, while chatting with my good friend Ed (an organic grower), the topic turned to plums and prunes. Ed said, "a plum is not a prune"

Me: Wait- what?
Ed: A plum is not -necessarily- a prune.
Me: But aren't prunes just dried plums?
Ed: It can be. But a prune is a specific variety of plum.

Who knew? I thought a prune was the dried version of a plum, just like a raisin is the dried version of a grape.

I also thought that the reason we are seeing more dried fruits labeled as "dried plums" instead of "prunes" was entirely a marketing gimmick. You can read more about the re-branding of prunes here, and here.

After the conversation with Ed, I wondered what a fresh prune looked like, and if I'd ever see one.

About a week later, Joan and I were at Costco, and guess what? Fresh prunes:
Here is what one looked like at home, next to a plum:
Check it out! They are different.

Here is what the prune looks like inside:
I'm sure there are different varieties of prunes, and they probably are not all this exact size or color. This one is an "Italian Prune"- but grown in the USA- ha. (the more I learn about food, the more I realize names and labels don't mean much, if anything. Labels are designed for marketing, not information).

So- in Ed's words: "all prunes are plums, but not all plums are prunes." I feel like I need a Venn diagram for that.

OK, I am a total geek : )
