Brine time can flex from 1-4 hours depending on how much time you have — 2 hours is the sweet spot for flavor without over-tenderizing. Mustard amount can be adjusted from 2-4 tbsp depending on how thick a coating you like. If your oven doesn't have a true convection/fan setting, add 3-5 minutes to the bake time and check doneness a bit earlier just in case. Ovens vary, so start checking temperature at the 13-minute mark.
