Combine the water and cornstarch in a saucepan. Cook over medium heat, stirring constantly, until the mixture becomes clear and thickened.

Let the mixture cool, then transfer it to a blender. Add the garlic, yogurt, oil, vinegar, lemon juice, and salt. Blend until smooth. If needed, add 2 more tablespoons of water to reach the desired consistency.

Slowly drizzle in 1/4 to 1/2 cup oil while blending until the sauce reaches a creamy texture.
