Thank you sooo much!
One cannot help but suspect that some wit of a nurseryman selected the English name “Humbug” not only because the pear brings to mind the striped hard candy called that in Britain, but also because the fruit is a sham, a hoax, a humbug—its pretty appearance concealing an insipid flavor.
I got the impression, too. But then I’ve also read that it keeps until May without refrigeration. It could be, that the taste develops just before full ripeness, which may be a very short window before spoiling. This is the case of Comtesse de Paris. It is an excellent long storage pear. Good for breaking windows only, unless really ripe.
It is possible that hardly anyone eats it well-ripened because they just can’t wait and bite into the pretty thing - same as what happens with red fleshed apples. People can’t wait for the sugars to develop
Maybe I’ll invest those 13€ to find out…
