Use some Cowboy Southern Style Hardwood Lump Charcoal to light fire and let burn for 10-15 minutes. Once Charcoal is white hot, push into one pile for direct grilling.
Once Cowboy Charcoal is white hot, place the lobster tails flesh side down on the coals and cook for 2-3 minutes. While lobster are cooking, place sauce pan on coals to preheat.
Gently lift the tails and flip to cook on shells for another 7-8 minutes. Add to sauce pan all of your Hatch Chile Butter Sauce ingredients and let simmer for 2 minutes. Once simmered, lather the lobster tails in the butter sauce until the lobster tails are firm and white.
