Grillable

“Grillable” (or “grill-able,” meaning a food that’s able to be heated on a grill) is a word that’s not in many dictionaries. A linguistic book published in 1974 declared: “But in the field of culinary terms, it (”-able”—ed.) is not used. There is no *fryable, *bakable, *grillable.”
 
“Grillable” is cited in print by 1914, but the word didn’t become popular until the 1990s, with the explosion of books about grilling. Meat and fish are popular “grillables.” The word can be used as an adjective (“grillable meats”) or a noun (“grillables”).
