Oyster mayo served on savory pork might just be the best thing since sliced bread as the saying goes. Once matched on a roll with cabbage, and pickled red onions you are very near perfection.

ChefSteps has kindly shared their favorite sous vide method for making oyster mayo. The results, as always, are outstanding. Enjoy!
