The Best Charcoal Grills And Charcoal, According .

19-05-2020· Once the coals are hot, dump them into the grill, Moore said. Another tool is a charcoal igniter, a device with a heat fan that you place directly onto charcoal, and it heats within a few minutes. No matter which way you light your charcoal grill, Patridge urges grillers to use their time at home during the coronavirus lockdown to experiment and break the rules when cooking out.
