Easy and economical, Refrigerator Dill Pickles are tangy, zesty and crispy. No one will believe you made them yourself! All you have to do is combine the cucumbers, dill, onions and garlic in a large bowl and set them aside. Combine vinegar, sugar, salt, mustard seeds, coriander seeds and dill seeds in a heatproof bowl. Add hot water and stir until sugar dissolves and liquid is clear. Cool to room temperature. Combine the two compositions and over them with a plate to weigh them down and keep them covered in brine. Cover bowl with plastic wrap and refrigerate overnight, stirring once or twice!
