In a food processor, combine the 2 cups of chickpeas, tahini, lemon juice, minced garlic, ground cumin, and a pinch of salt. Blend until smooth.
With the processor running, slowly add the ice water until the hummus reaches a creamy and silky consistency.
Taste and adjust the seasoning as needed. If the hummus is too thick, add a little more water or lemon juice.
Transfer the hummus to a serving dish and smooth with the back of a spoon, creating a well in the center.
For the spiced chickpeas, heat 1 tablespoon of olive oil in a skillet over medium heat. Add the 1 cup of dried chickpeas and toast them until golden and crispy, about 5-7 minutes.
Stir in the smoked paprika, ground cumin, coriander, cayenne pepper, and a pinch of salt. Cook for an additional 2-3 minutes, until the spices are fragrant.
Spoon the spiced chickpeas onto the hummus in the well you created.
Generously drizzle olive oil over the hummus and spiced chickpeas.
Garnish with chopped parsley before serving.
