Follow The Directions

01

Step

5 mins

Preheat an outdoor grill for medium-high heat and lightly oil the grate. (5 minutes)

02

Step

10 mins

Rub a generous amount of salt over each steak. Spread a thick layer of mustard on each side of each steak. Sprinkle tea leaves over each steak until mustard is completely covered. (10 minutes)

03

Step

20 mins

Cook the steaks on the preheated grill until desired degree of doneness is reached, 5 to 10 minutes per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C) for medium-rare. (10-20 minutes)

For a richer flavor, use a high-quality loose leaf black tea instead of tea bags.
Experiment with different types of mustard, such as Dijon or stone-ground, to customize the flavor profile.
Allow the steaks to rest for 5-10 minutes after grilling before slicing against the grain to maximize tenderness and juiciness.
