I'm a new brewer, 3 beers in, and recently just bought a bayou classic burner because my electric stove wasn't cutting it. I brewed my first batch on it but had a hard time controling the temp while steeping grains. I started at 160 but it quickly went to 180. I turned the burner don but it stayed at that temp. Any ideas on how to better control the temp? Maybe turn the burner off or take it off and monitor it? Thanks for the help
