Is there an English word for the Spanish pepper called Ñora?
Almost certainly not. They look and sound a lot like cherry peppers, aka pimiento peppers, but are apparently a distinct cultivar. With the exception of commercially important (“Maris Piper”) or widely renowned (“Honeycrisp”) names, cultivars tend to be quite local in penetration, and are unlikely to have translations in other languages.
You’d probably do fine to substitute cherry peppers, if you’re trying to make a particular recipe which calls for them.
