Bring a 6- to 8-quart pot of water to a boil over high heat.
Meanwhile, in a small bowl, combine the butter, Dijon mustard, maple syrup, thyme, stone-ground mustard, and 1/4 tsp. sea salt. Mix vigorously with a silicone spatula until combined.
Boil the corn until just tender, about 3 minutes. Remove the corn from the pot and let rest for a few seconds to allow some of the water to evaporate. Slather each cob with at least 1 Tbs. of the butter and serve immediately.
