In a large food processor, fitted with a blade, add the hummus ingredients (chickpeas, chopped pickles, brine, garlic, olive oil, tahini, dill, and pepper). Run the food processor to blend until the hummus mixture is smooth.
Test, and if it’s too thick, add a very little bit of the chickpeas canning liquid. Run the processor again until you achieve the desired creamy consistency. Adjust seasoning as needed.
Transfer the hummus to a serving dish and cover tightly. Chill a few minutes before serving. Uncover and smooth the surface of the hummus and drizzle a bit of extra virgin olive oil. Garnish with fresh dill or another herb if you like.
Enjoy with sliced cucumbers, pita bread, or pita chips.
