Add the mayonnaise to the mixing bowl (1 cup for small portions or the entire jar for large portions).
Add the chili sauce to taste, typically using a 1:2 ratio with the chili sauce (1 part chili sauce to 2 parts mayonnaise).
Add a touch of sesame oil for extra flavor (1 Tbsp for every 1 cup of mayonnaise).
Mix all ingredients together with a spoon or spatula and taste test.
Adjust the amount of chili sauce or mayonnaise based on your heat tolerance.
Transfer the spicy mayo to a zip locked bag or sauce bottle for easy squeezing.
Store in the refrigerator for at least 1-2 weeks.
