Put all the ingredients, except the sunflower oil, in the blender and mix on medium speed.
While mixing, slowly add the oil.
Put the mayonnaise in a bowl and then, in the fridge where it will become thicker.
For the potato salad
If you add the leek, cook it in hot water and remove it after 3 minutes.
In the same water, continue cooking by adding the potatoes. Boil them until soft, but still firm.
Cut the vegetables into small pieces and the radishes into thin slices.
Put them in a bowl and add the mayonnaise, pepper, smoked paprika and kala namak, which will give the egg flavor. Mix them all together.
Put them in the fridge for a while so the aromas and flavors are well blended.
Enjoy your salad cold or hot.
Notes
Tips:
If the milk is watery, which means it does not contain enough soy (see on the ingredients of the package), the mayonnaise will not thicken.
We use soy milk and not some other type of plant-based milk because soy (like egg) contains lecithin which is an emulsifier.
If the milk is cold, the mayonnaise becomes thicker faster.
We choose sunflower oil, and not olive oil or other type of oil, for its neutral taste. In addition, when you blend olive oil, it becomes a bit bitter.
If the mayonnaise tastes a bit rough, you can add a little more sugar or sunflower oil.
If you want the texture even tighter, add a little more sunflower oil.
