It sells bell peppers, roasted peppers, pimientos, and sweet potatoes.
The flesh of the pimiento is sweet, succulent, and more aromatic than that of the red bell pepper.
Originally, the pimiento was hand-cut into tiny pieces, then hand-stuffed into each olive to balance-out the olive's otherwise strong/salty flavor.
More recently, for ease of production, pimientos are often pured then (re-) formed into tiny strips, with the help of a natural gum (such as sodium alginate or guar gum).
