Start by rinsing and draining the red kidney beans well.
Add the kidney beans, minced garlic, tahini, cumin, sumac (or smoked paprika), lemon juice, salt, and black pepper to a food processor.
Slowly pour in the ice-cold water and blend until smooth and creamy. Scrape down the sides as needed.
Taste the hummus and adjust the salt, pepper, or spices if needed.
Transfer to a bowl and serve with vegetables, pita, crackers, or spread on sandwiches and wraps.
Notes
Adjust the consistency - If the hummus is too thick, add 1-2 tablespoons of water and blend again until you reach your desired consistency.
Blend longer than you think - Let the food processor run for an extra 30 to 60 seconds after the hummus looks smooth. This helps make the texture even creamier.
Use your favorite spices - add chili flakes for spice, curry powder, or your favorite seasonings.
Allow to rest - If you have time, let the hummus sit in the fridge for about 20 minutes before serving. The flavors will blend and develop more depth.
You can use an ice cube instead of ice-cold water.
