Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
New Way to Make Mayonnaise
Ingredients
Directions
Prepare
Put one whole egg in a bowl.
Make the mayonnaise
Beat the egg into one pint of Wesson or olive oil, adding lemon juice, salt, and pepper to taste.
Add one tablespoon of boiling water for each cup of mayonnaise, beating in.
Chill
When cool, place on ice.
Nutrition, whole recipe (rough)
Counts 4 of 5 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 4 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Egg | 1 large egg (50g) | 78 |
| Lemon | juice of 1 lemon (48ml) | 12 |
| Black Pepper | 1 tsp ground (2.3g) | 6 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 2-nonenal (fatty, green).
Egg and lemon barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wesson oil
- Forms most of the mayonnaise, giving it its body and rich, smooth texture.
- Egg
- Its yolk emulsifies the oil, holding the oil and water droplets together so the mixture thickens.
- Lemon juice
- Adds acidity that brightens the flavor and balances the richness of the oil.
The step that matters
Beat the egg into the oil. The yolk can only hold the oil in a stable emulsion if the oil is added gradually while beating. Adding it too quickly overwhelms the yolk, so the mixture stays runny or separates.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
