What varietal? Commercially raised a sterile hybrid pepper of a cross of green pepper with Jalapeno. Great flavour, and they had no—zero heat. Branded as “Fooled You!” Good and Foolish Bread and Butter Peppers.
You could take one- red matured looking just like a Jalapeno- and munch down in front of very impressed friends.
Pickled in bread & butter sweet (with a little hot) liquid.
Yes I grew those too. I love them.
They have several names..
Nadapeno
Coolapeno
Fooled You Peppers
Just don’t mistake them for the Fresno Pepper.
One of my all time favorites is the Shishito pepper. Fry them up fresh and eat them like poppers.
