The 1989 Baird and Thieret paper referenced in the article might be my favorite research paper ever. I read it soon after it came out in the reading room of my college library. After finishing it, I genuinely was uncertain whether it was a real paper or a Borgesian spoof. Bletted for months before it's edible? A Shakespearean insult? On the Unicorn Tapestry and I'd never heard of it?
Since then, I've confirmed that it actually exists. I've even tasted the fruit. It's... OK. It's a reasonably tasty spiced brown apple/pear sauce with a grainy texture, but with the spices already built in. I've got my own tree planted---more for the novelty than desire for the fruit---and hope I'll finally get a few of my own this year.
I've known it all my life since my grandfather had a Medlar (Mispel) in his back yard. They use to make great spicy compote from the fruit.

> Medieval Europeans were fanatical about a strange fruit that could only be eaten rotten.
To be clear, you do not let the medlar "rot" before eating.
Rotting involves decay by microorganisms -- fungi, bacteria, yeasts.
What the medlar does is totally different. It has an enzyme within it that continues to break down the fruit, so it goes from rock hard to soft and edible.
Because this is a different chemical process from traditional ripening, someone gave this the name "bletting". But it's definitely not "rotting".
There's an evolutionary theory that by delaying when the fruit could be eaten, it could attract animals in the winter that would be more likely to eat it (since other fruits were no longer available) and potentially transport its seeds longer distances.

Quince and some persimmons are also commonly bletted before consumption... so it's not even unique to medlars.

Also, frost will trigger the process, so nowadays you don't need to wait so long for the fruit to decide to be edible if you put it in the freezer for a bit first.

You can say a fruit is ripening, rotting, or bletting.

Bletted.

Different from ripening? Ripening is a process in which enzymes break down cell walls, acids, and tannins, and break starches into sugars, isn't it? Bletting appears to be a second one.
crazygringo 21 hours ago [-]
For whatever reason, ripening is defined as a hormonal process generally triggered by ethylene. Bletting is different from that, and happens after the hormonal ripening. It's more of a biological distinction than a culinary one, I think.

Speaking of forgotten fruit.
The evolution of watermelon is fascinating. It happened in (relatively) recent human history and has really stark changes.
There are old paintings of watermelon from the 17th century and it looks nothing like modern watermelon. [1]
Another wild human guided evolution is the evolution of the chicken. [2] That one literally happened in the last 100 years. A modern chicken is 3x larger than a chicken from the 1950s.
I have trouble believing this, though I've heard it before. The watermelon in the painting looks exactly like the insides I've seen in my homegrown watermelons when things don't go right, i.e. under watered, not fully pollinated, or just underripe.

No, their point is that the painting isn't evidence of changes, because they've seen modern watermelons that look the same.

If your watermelons look like [1], you are a bad gardener. Mine look supermarket-ready.
And I've never heard of a feral chicken. How do they survive? And where? They are a fully domesticated species, with almost no defences. Flying 8' up to a branch is a major effort for them. My neighbor loses about half of them each year to predators, and they are kept in a coop at night.

Yeah, it's not that hard to grow good garden fruits and vegetables. Plant them at the right time in good soil, keep the weeds down (that's 95% of the job in the Midwest US), water them if it gets too dry, and watch out for pests. Do that, and your produce will be as good or better than what you can buy.
I'd like to see a feral chicken too. Maybe they exist in regions with no natural predators. If mine aren't well-protected, I lose them to foxes during the day or coons at night.

While "nespole" is apparently sometimes called "Japanese Medlar" in English, they are more usually called "Loquat" (Eriobotrya japonica): https://en.wikipedia.org/wiki/Loquat
You might mistake them in a black-and-white photo, but otherwise are easily distinguished. Neither is well known in most of the US, but the loquat is commonly grown in California yards while the medlar is a true rarity here.

How about the popular fruit with a vulgar name
> The English word "avocado" comes from the Spanish word aguacate, which comes from the Nahuatl (Aztec) word ahuacatl. This Nahuatl word translates to "testicle". The name was likely given to the fruit by the indigenous Nahua people because of its suggestive shape, and the fruit's reputation as an aphrodisiac.
crazygringo 24 hours ago [-]
Wherever you got that from has it backwards (it's a myth commonly repeated). The fruit name came first:
> In Molina's Nahuatl dictionary "auacatl" is given also as the translation for compañón "testicle", and this has been taken up in popular culture where a frequent claim is that testicle was the word's original meaning. This is not the case, as the original meaning can be reconstructed as "avocado" – rather the word seems to have been used in Nahuatl as a euphemism for "testicle".
Also "avocado" is an older variant of "abogado," which means lawyer in Spanish. English must have mixed these up.

And French completed this merge by having both "lawyer" and "avocado" translate to "avocat".

If I understand correctly, that's also where the Dutch "advocaat" liqueur comes from. They were trying to reproduce sweet avocado drinks, there were no avocados in Europe, so they made something up they thought tasted similar.

My partner and i used to harvest medlars from a community garden. We made medlar jelly from them when they had bletted. It kinda tasted like tea. Must be the tannins. We ended up making a sweet chilli sauce from it when we still hasnt eaten it when our chillis became ripe the following summer

Actual credit for the hero-image engraving is Crispijn van de Passe (attributed, at least), sometime between 1600–1604, currently in the Rijksmuseum in Amsterdam. Besides the misattribution, even the description is wrong: only the right drawing (label "18") is the "Mespilus germanica" the article's about—the left one is an unrelated flower, drawn on the same page. (Or however you say it, for an engraving).
It's one plate from a large collection of botanical engravings, "Hortus Floridus" (published 1614–1616) you can browse on archive.org (I link below).
Seems to get heavily mixed in naming with the genus Vangueria in the family Rubiaceae, since they're frequently named Medlar, and have edible fruit, just happen to be mostly from Africa. Really confusing, since they look similar, have similar food, yet apparently different genus, family, and order. Don't cross over until they get all the way up to Clade: Eudicots. Apparently they're attached to bad luck and misfortune, so maybe they got a cursed botanical classification.
