While tahini is a traditional ingredient in hummus that contributes to its smooth and creamy texture, you can still achieve a similar consistency without using it. Increase the amount of extra virgin olive oil if you want an even creamier texture. Olive oil adds richness to the hummus and helps to achieve a smoother texture. Alternatively, you can incorporate creamy nut butter like almond, cashew, or sunflower seed butter. They contribute a silky texture and a hint of nuttiness to the hummus.
