- In a small bowl, combine 1 tablespoon sugar, 1 tablespoon lime juice, 1/2 teaspoon salt, and 1 teaspoon warm water. Stir until the sugar dissolves, then set aside. 
- Pour 150 mL garlic-infused olive oil (or regular olive oil) into a small bowl for easy access. 
- Crack 2 eggs, separating the yolks from the whites. Place the yolks in a deep-bottom mixing bowl. 
- Use a small hand-held whisk or egg beater to begin whisking the egg yolks until they are smooth. 
- While whisking continuously, use a teaspoon to slowly drizzle in a small amount of oil. Whisk for about 30 seconds before adding more. Be careful not to add too much oil at once. 
- Gradually repeat step 5 until the mixture becomes thicker and smoother. As it thickens, you can begin adding slightly larger amounts of oil each time while whisking well to maintain consistency. 
- Continue whisking and adding oil in this manner until all the oil is incorporated and the mayonnaise is thick and smooth. 
- Once the mayonnaise is ready, add the mixture of sugar, lime juice, salt, and water. Adjust the taste if needed. Whisk well until fully combined. 
- Vietnamese Mayonnaise is now ready. Transfer it to a sealed jar or container and store it in the fridge. The mayonnaise will last for about 1-2 weeks.
