Rinse and drain white beans in a fine mesh strainer.
Then add to a food processor or blender along with pumpkin, lemon juice, tahini, sea salt, cumin, smoked paprika, nutmeg, cinnamon, and cayenne (optional).
Purée until creamy and smooth, scraping down sides as needed.
Taste and adjust seasonings as needed, adding more salt for saltiness, lemon for acidity, cumin or paprika for smokiness, tahini for nuttiness, or cayenne for heat.
Serve immediately with pita chips and vegetables of choice (see notes for pita chips). Alternatively, refrigerate until chilled – about 3-4 hours – for a thicker, creamier dip.
Store leftovers covered in the refrigerator up to 5-7 days.
