For the quick pickles: Add the vinegar, 1/2 cup water, sugar, mustard seeds, salt, garlic and bay leaf to a saucepan and bring to a simmer. Once the sugar has dissolved in the simmering liquid, add the cucumbers and dill to a heat-proof container and pour over the pickling liquid. Let sit for at least 10 minutes. Chop 2 tablespoons for the dressing, and reserve the rest for serving.
For the 18000 island dressing: In a food processor add the mayonnaise, ketchup, jalapenos, chopped quick pickles, Dijon, garlic and some salt. Puree, taste and adjust seasonings if necessary.
For the burgers: Heat a cast-iron skillet or large heavy griddle pan over medium-high heat.
Combine the chuck and brisket and form into 4 balls with your hands.
Add the canola oil to the heated griddle. Place the burger balls on the griddle and sear for 1 to 2 minutes per side. Then, using a spatula, press the balls down, flattening them down as you spread them out. You want a thin, crusty burger and that's all about creating surface area, so press away. Let the burger get a nice char on one side, and then flip so they get nice and crusty brown, 4 to 5 minutes per side.
Butter and toast, or griddle, the sesame seed buns. Once toasted, add 1 to 2 slices cheese to each bottom bun. Place the burger on the bottom bun with the cheese. Top the burger with some tomato slices, quick pickles and iceberg lettuce. Spread some of the 18000 island dressing on the top bun and top the burger. Appreciate the old school classic.
