Combine all —silken tofu, olive oil, vinegar or lemon juice, Dijon mustard, salt, and optional turmeric—in a high-speed blender. 2.
Turn the blender to medium speed and blend for 1-2 minutes until the mixture is moving smoothly. 3. Stop the blender and use a rubber spatula to scrape down the sides of the container, ensuring everything is incorporated. 4. Resume blending on medium-high for a full 3 minutes. This extended blending time is the secret to achieving a perfectly creamy, airy consistency. 5. Stop and scrape the sides one last time, then blend for one final minute until completely smooth. 6.
Taste and adjust seasoning, adding more salt if necessary.
Serve immediately or transfer to a sealed jar and refrigerate for up to 5 days.
Don't skimp on the blending time! The extended blending is what whips air into the mixture, creating that perfectly light and creamy texture.
