I have soy lecithin with me. How do I blend this with water and oil to make vegan mayonnaise? I have tried a lot of times but every time I get a thin oily watery stuff.
The procedure is-
1)Mix 2 tbsp lecithin with 3 tbsp water.
2)Add the mixture with 1 tbsp oil and mix in the blender.
3)Repeat step 2 four times.
No matter how much oil I add, it doesn't work. When I use homemade soymilk instead of water+lecithin, it works.
When you add soy lecithin to your water-oil mixture and agitate it, it only helps to combine oil and water but does not give it the consistency of egg-based mayonnaise. It's way more fluid/watery. This video explains the chemical process behind this emulsion and gives you an idea of how this mix would look like and why. If you are really interested in the chemistry behind it.
To give your vegan mayo the body and stability of egg-based mayo when mixing it, you would need to add a base like vegetable or tofu when mixing soy lecithin, oil, and water.
The Soya milk works as it contains natural emulsifiers which bind the oil to make it nice and fluffy and mayo-like.
I found this blog post very helpful when making vegan mayo with a friend for the first time. The eggplant really does the trick!
