Which are better, cast iron or porcelain-enamel cooking grates?
Both grate types have their merits, so it is mostly a matter of personal preference. Cast iron grates give you better sear marks, and hold the heat longer so you don’t have to cook with higher temperatures. Cast iron grates have a longer warranty, but require more maintenance. Porcelain grates are durable, give wide grill marks and require less maintenance.
