    This is interesting. I wonder where Australian citrus fits in with this? Do you know about finger limes aka caviar limes fit in this image?

      This project was about how citrus affected Sicily for a 1000 years. I have been pondering the possibility of continuing citrus travelogues elsewhere; there are so many fascinating stories: Algeria, Australia, Philippines, New Orleans, China, Japan, etc, etc. But your note makes me happy because once I finished this series, I started trying every citrus not related to Sicilian history I could get my hands on. Finger limes are one of my favorites. Bergamot is so weird, and it is the best marmelade. Regardless of whether I do more citrus travelogues, I will get to a global Citrus poster within a year.

      That is a really cool chart...I wish it would include micrantha, which it references but doesn't include in the triangle...but really cool way to visualize it.

    Only tangential, but it reminds me of how the cure for scurvy was found, then lost. https://idlewords.com/2010/03/scott_and_scurvy.htm Basicly, the danger of using something you don't understand. It mostly works, Until it doesn't and you can't fix it.

    Aren't all of the citrus fruits native to South East Asia?
    • erik-gauger 1 hour ago
      Yes, the series is about how citrus from Southeast Asia impacted every aspect of Sicilian culture, cuisine and politics for 1,000 years. Let me know what you think of Chapter 5, which is about the wild fruits.

      Many of the hybrids originated elsewhere.

      "Grapefruits originated in Barbados in the 18th century."

        Yup, and that it what the series is about. Let me know what you think if you get a chance to read it.

    I love posters like this one!

    Unfortunately when I try to shop for them nowadays they're all AI slop. Is it too much to ask to get a nice Encyclopedia of Pastries poster? Apparently it is.

      Thank you! One reason hand-drawn posters are rare is how long they take. The citrus plate at the bottom of this page is 25 fruits and took me roughly 100 hours; my chili poster took about 500 because it was 176 fruits. Nobody does that work to make money on a poster. There has to be an underlying editorial reason to draw the thing in the first place. For me, I am like you...I always wanted to see these things as posters and they never existed. Speaking of pastries, that Great British Bakeoff must have thousands of those pastry and cake illustrations that they use to illustrate the show.

      You can get some decently high resolution images on Wikipedia commons which are scans of old hand drawn illustrations in books. Then (I know, I know) use an AI tool to enlarge the images to a high enough resolution that they print nicely. There are task specific tools just for enlarging that do a pretty decent job if you aren’t trying to go more than 2x. But the scans are usually enough that you only need to slightly enlarge them to get to a resolution that prints 300dpi at a reasonable size.

    I wonder if any Sumo or Tangelo is grown there. These are in season and available in the U.S. in the early spring.

    • erik-gauger 1 hour ago
      Great question. In Sicily, there is a specific tangelo called the Mapo, although it is a very small crop. Sumos are grown only in California, I believe. Here in Portland, we are just starting to get tangelos and sumos, but they all seem early and a little bland. In other month, it's citrus heaven. Since I just finished this series, I have been trying to taste any citrus I can. I love finger limes and bergamots.

    This doesn't actually answer the question. It lists the parentage of some other varieties, and then lists a bunch of blood oranges without saying where they came from.

    Claude can make some very interesing, informative, accurate sites to present information. This isn't an example.

    • erik-gauger 1 hour ago
      Hi, this is an epilogue from an 8 chapter series that explains all of those things. Note that there are chapter links to each of those 8 chapters. For the chapter on blood oranges, I spoke with agronomists, ecologists and historians, and sketched a blood orange grove. The fruits shown on this epilogue are the fruits that I discussed in the series.

        Good for you for doing all that prior to prompting your post.

        Would be nice if any of what you said was clear from the thing actually posted. Maybe a more detailed prompt next time?

        Posting the final post in a series and then expecting people on a random site to have read all prior series posts is not a good look.

        • erik-gauger 28 minutes ago
          Fair point that the page didn't stand on its own. I didn't submit it; it was written as an epilogue for people who had already read the series, so it assumed all of that context. It's the last page of a 30,000 word essay and was never linked as a standalone page. I've since added an intro explaining what it is, links to all eight chapters at the top, and where each fruit originated. I was at the theatre this evening, when I started seeing traffic and these comments, so I rushed home to make the clarifications.
