The basics of corned beef
Corned beef is a beef brisket that’s been cured in a brine with salt and spices. The beef sits in the brine for a few days, which tenderizes the meat and infuses it with flavor. Plus, it retains a pink color once cooked thanks to curing salt within the brine. This process results in juicy corned beef that’s delicious, especially enjoyed with tender vegetables like cabbage, potatoes and carrots.
