Why it works: Pepper and lemon 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 ↓
Hollandaise Sauce
Ingredients
Directions
Make the base
Combine butter, lemon juice, egg yolks, cayenne pepper, boiling water, and salt in a bowl.
Beat the butter to a cream.
Add the egg yolks one by one, beating after each addition.
Add the lemon juice, pepper, and salt, beating thoroughly.
Cook over water
Place the bowl over a saucepan of boiling water (bain-marie).
Beat with an egg-beater until the mixture begins to thicken, about one minute.
Add the boiling water, beating continuously.
Stir until the sauce thickens to a soft custard consistency.
Stir a few minutes after removing from the heat, being careful not to overcook.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Egg | 1 large egg (50g) | 78 |
| Lemon | juice of 1 lemon (48ml) | 12 |
| Cayenne | 1 tsp (1.8g) | 6 |
| Black Pepper | 1 tsp ground (2.3g) | 6 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

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
- Eggs
- Egg yolks emulsify with the butter and thicken into a smooth, custard-like sauce as they heat.
- Butter (in the method)
- Adds fat and richness, and its emulsion with the yolks gives the sauce a silky texture.
- Lemon juice
- Adds acidity that brightens the rich butter and balances the sweetness of the yolks.
The step that matters
Stir over gentle heat and remove before overcooking. Egg yolk proteins set as they warm, thickening the sauce. Too much heat or too long over the water bath makes them tighten and curdle, so the sauce turns grainy or scrambled instead of smooth.
