I gotta bring my tape measure out to the Jalapeño patch, see how tall they are. Some of my Zapos seem pretty tall, mostly on the shady end of the bed. Others are short. None of mine are nearly as bushy as IdahoLewis's plants; those look great.... But my bushiest Zapos are also the tallest, so I guess the shade provided by that obnoxious fig tree is beneficial?
But yeah, I will eat the occasional dark green Zapotec from my plants if I inadvertently knock one off while wedding, or just if the mood strikes. Simply put, the green pods at the market are just lame. Little heat, less flavor. So, yeah, I grab the occasional greenie from the Garden just for the superior heat and taste.
I suspect my wife has been smuggling
quite a few green Zapotecs this year. She really likes'm green, plus she's not one for patience.
But, other than that, I wait for >98%*** of my Jalapeños to turn red before I pick them, for all the same reasons SMDSauce listed. Same is true for Serranos, and to a slightly lesser degree, Poblanos and such. But every unripe Chinense I've eaten has been a disappointment, as have the unripe Baccatums and most all the annuums, excepting those mentioned above.
Why pick'm before their time?
***Last year, the local Cantina actually asked me to pick them green. So, there's another exception. I cane thru with a shitpile of green Jalapeños and Serranos for them. Served like such a waste, but they put them to good use.
