Place the chickpeas, red pepper, paprika, and cumin in the bowl of a food processor and blend until a stiff paste forms.
Keep the food processor running as you add the tahini, lemon juice and garlic.
Slowly add the ice water and continue to blend until the mixture is smooth. Season with salt to taste.
Refrigerate in an airtight container for up to two weeks.

Roast for 30 minutes, until crispy. Remove from oven and let cool.
