My asian mayo:
Ingredients: 1 egg yolk. pinch of salt. squeeze of lemon juice. 150ml-250ml vegetable oil (not olive oil). Lime/lemon juice. 1 Kaffir Lime leaf shredded. 1/4-1/2 tsp chilli flakes. Splash of fish sauce. 1/4 tsp ground garlic(paste).
Method: Whisk egg, salt and squeeze of lemon until combined. Add about a tablespoon of oil. Whisk like mad until incorporated. Add another tablespoon of oil and whisk madly again. Repeat this about 8-10 times. Then add a couple of tablespoons of oil at a time. Making sure each time you whisk until you cannot see liquid oil and you have a thick yellow mayo (EVERYTIME you add oil). Once you are happy with your mayo, mix in the rest of the ingredients and season to taste.
Try making your own mayo!!! Takes about 5 mins.
