I usually cook this meal using either my Crock-Pot or oven-baked method, but this time I was anxious to see what results I could get from the Instant Pot. To my surprise, using an electric pressure cooker yields exceptionally tender meat; now I have another go-to method in my repertoire.
Purchasing corn beef
Look for a brisket that’s flat cut or point cut on the packaging with minimal fat cap. Some come pre-trimmed. I bought a 3 ½-pound brisket that came with a seasoning packet, but once I cut away the extra fat, it hit 2 pounds on my kitchen scale.
Therefore, if the only choices you have at the market are fatty, buy a more substantial weight and plan for it to get smaller after trimming. The thickest part of the meat was 1 ½ inches, so if your cut of beef is thicker, add about 5 more minutes of cooking for every additional ½ inch
