Start by draining and rinsing the chickpeas under cold water. This helps to remove excess sodium and ensures a cleaner flavor. Mince the garlic and set it aside. Dice your dill pickles for the topping.
In a food processor, combine the drained chickpeas, tahini, minced garlic, dill pickle juice, dill relish, olive oil, lemon juice, dried dill, kosher salt, black pepper, and crushed red pepper flakes.
Pulse the mixture until it starts to come together. Gradually add ice water, one tablespoon at a time, while processing. Continue blending until the hummus reaches your desired consistency—smooth and creamy.
Taste your hummus and adjust the seasoning if necessary. You can add more salt, pepper, or pickle juice according to your preference.
Transfer the hummus to a serving bowl. Top it with the diced dill pickles and a sprinkle of fresh dill for an extra burst of flavor and color. Drizzle a bit of olive oil on top for visual appeal.
