It is nearly impossible to find the jalapeño bun that Rachael’s uses, so I opt for a quality brioche hamburger bun. Quality Louisiana oysters are essential; be sure to look for large, plump oysters. Peanut oil is traditional for frying, but if you have allergies, feel free to use vegetable or canola oil. I like the blend of flour and cornmeal, but there are many packaged Cajun breading mixes on the market that will work just fine. The simplicity of mayonnaise as my dressing of choice goes back to my childhood, but it’s okay if you opt for tartar, rémoulade, or any commercial seafood sauces.
