Rinse and drain the garbanzo beans thoroughly under cold water, shaking the colander to remove excess moisture—this prevents the hummus from becoming too wet. Mince the garlic cloves finely, dice the pickles into small, uniform pieces, and chop the fresh dill. Having everything prepped and ready will make the blending process quick and seamless.
Add the drained garbanzo beans, minced garlic, tahini, lemon juice, pickle juice, cumin, and salt to a food processor. Blend until completely smooth, scraping down the sides as needed—this usually takes 2-3 minutes. I like to add the pickle juice early in the blending process because it helps create a creamy texture while adding that signature tangy flavor throughout, rather than just at the end.
With the blender still running, drizzle in the olive oil and add water 1 tablespoon at a time until you reach your desired consistency—the hummus should be creamy and spreadable but not watery. Stop the blender and fold in the diced pickles and fresh dill by hand using a spatula; this preserves the texture of the pickles so you get little bursts of flavor rather than them blending into a paste.
Taste the hummus and adjust the seasoning as needed—you may want to add more salt if your pickles weren't particularly salty, or a squeeze more lemon juice for brightness. Transfer to a serving bowl and drizzle with a bit more olive oil if desired. I always taste before serving because pickle brine varies by brand, and I want to make sure the flavors are balanced and the dill comes through clearly.
