I struggled with knowing when to flip the meat I was cooking in a pan or on the grill until I gifted myself online culinary classes with Chef Todd Mohr in 2016.
Chef Todd is a certified culinary educator who frees home cooks from recipes by helping them learn techniques and methods to put amazing meals on the table.
You can learn when to flip when cooking meat in this short YouTube video by Chef Todd. It changed my life (and cooking habits) forever.
PS ... when the meat reaches the visual indicators Chef Todd shares, you will find it easily releases from the pan (another indicator of when to flip it!)
