For the Oklahoma Onion Smash Burgers, use a mandoline to quickly and evenly slice the onions. For the comeback sauce, adjust the level of heat by increasing or decreasing the amount of hot sauce and cayenne to suit your palate. For the spiced garlic dill pickles, to submerge the cucumbers in the brine, find a small plate or saucer that fits into your container. Press it down over the cucumbers to submerge, then top with a can or other heavy object.
