INFO:
To make mayonnaise, you'll need 3 eggs, lemon juice, white vinegar, and some high-quality olive or vegetable oil. Crack the eggs and separate the yolks from the whites, putting the yolks in a heat-safe mixing bowl. To the yolks, add 2 tbsp of white vinegar, 2 tbsp of lemon juice, and 2 tbsp of water and then mix well. To reduce the risk of salmonella food poisoning, double boil this mixture for about 1 minute. Then, slowly add in 1 cup of vegetable or olive oil while mixing constantly.
