Prepping Asparagus
In a small bowl mix the rub ingredients. Lightly brush both sides of the filets with oil and season evenly with the rub. Allow the filets to stand at room temperature for 15 to 30 minutes before grilling.
Prepare the grill for direct cooking over medium heat (180°C to 230°C). If you’re using a charcoal grill, keep a small part of the charcoal grate clear of briquettes as a safety zone of indirect heat.
In a small saucepan combine the vinegar, water, shallot, tarragon, salt and pepper. Bring to a simmer over medium heat on the stove and continue cooking until the mixture is reduced to 3 tablespoons. Remove from the heat and allow to cool for a few minutes.
In a small bowl whisk the egg yolks and then whisk in 1 tablespoon of the vinegar mixture. Whisk the egg mixture into the remaining vinegar mixture in the saucepan and whisk until smooth. Place the pan over low heat and whisk the mixture constantly until it thickens to the consistency of mustard. Immediately start drizzling the melted butter in a thin stream into the pan, whisking constantly, until the mixture reaches the consistency of thin mayonnaise. If at any time the sauce looks like it is separating, remove the pan from the heat and continue whisking to cool it down. Scrape the sauce into a small bowl and set aside at room temperature.
Brush the cooking grates clean. Grill the filets over direct medium heat, with the lid closed, until cooked to your desired doneness, 11 to 13 minutes for medium rare, turning once or twice (if flare-ups occur, move the filets temporarily over indirect heat). At the same time, grill the asparagus and crab legs over direct medium heat until the asparagus is crisp-tender and the crab is heated through, 6 to 8 minutes, turning once or twice.

Remove everything from the grill and let the filets rest for 3 to 5 minutes. Cut the asparagus into 5 centimetre lengths and keep warm. Cut open the crab legs with kitchen shears and remove the meat.
