Cubanelles can be 4 to 6 inches (10 to 15 cm) long, tapering towards the end, and up to 2 1/2 inches (6 cm) wide at their widest point. The colours will range from pale green to yellow to orange to red. The red ones are the fully ripe ones, though they are usually picked and sold as light green.
They are sweet, mild peppers with more flavour than Bell peppers. They also have a lower water content than Bell peppers, so are good for frying and other cooking uses.
The skin can be a bit tough when cooked.
Store yellow and green ones in fridge in a plastic bag for up to a week; red ones will keep only a few days.
Despite the name “Cubanelle”, this pepper was actually developed in Italy. Called “pimientos de cocinar” (“cooking peppers”) in Puerto Rico.
