In a bowl, mix unsalted butter, garlic and parsley. Then add lemon juice, salt and pepper. Roll butter into a log shape in parchment or non-stick aluminum foil and place in refrigerator for 1 hour. (This can be done up to 24 hours before cooking)
While butter is cooling, start to season NY strips with salt and pepper.
Light the Cowboy Hardwood Lump Charcoal in a charcoal chimney or mound inside your grill and let burn for 10-15 minutes.
Place cast iron skillet over fire at least 5-10 minutes before cooking. (Optional: For more added fun place the cast iron directly on top of the coals!). Add 1/2 stick of butter on cast iron 2 minutes before you start cooking.
Once fire is medium to medium-high heat, add steaks to cast iron and let cook on one side for 3 minutes. Flip steaks and place Herb Butter on top of each steak. With a spoon (being very careful), baste the steaks with the melted Herb Butter for 3-4 minutes.
Pull steaks off grill and let rest for 10 minutes. Serve and enjoy!
