We bought a Capital Culinarian Rangetop and I bought my wife a large cast iron griddle to cover the burners ( 2 burner griddle ). The burner grates are approx 11.25 inches by 22 inches. However, the griddle I bought was way too big ( 24 inches by 16 inches ), and I am now seeking a suitable alternative that will fit our burners. Our burners get REALLY hot and I'd prefer as large a griddle as reasonably possible. Thx in advance!
