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 ↓
Hollandaise Sauce
Ingredients
Directions
Prepare
Melt the butter in the microwave or on the stovetop in a small saucepan.
Pour a small amount of water into a medium-sized double boiler, ensuring the water does not touch the bowl.
Bring the water to a simmer over medium heat, then reduce the heat.
Make the sauce
Place egg yolks and the dry and liquid ingredients into the bowl and whisk for 1–2 minutes.
Gradually add the melted butter a little at a time, whisking until the butter is well incorporated and the mixture expands.
Place the mixture over the simmering water and whisk for 3–5 minutes, until the mixture is thick enough to coat the back of a spoon.
If the mixture becomes too thick or separates, add very small amounts of hot water until corrected.
Nutrition, whole recipe (rough)
Counts 6 of 7 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 6 portions
| Ingredient | Portion assumed | kcal |

| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |
| Lemon | juice of 1 lemon (48ml) | 12 |
| Chili | 1 tsp (2.7g) | 8 |
| Black Pepper | 1 tsp ground (2.3g) | 6 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and thicken into a smooth, rich sauce as they cook gently.
- Unsalted butter
- Adds fat and richness, forming an emulsion with the egg yolks for a silky texture.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness of the butter.
The step that matters
Whisking over the simmering water. Egg yolks thicken gently at low heat, but if the water is too hot or the bowl touches it, the yolks can scramble. Constant whisking keeps the heat even and the emulsion stable.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, butter, lemon, pepper):
- Parsleyfits better
- Tarragonfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against egg, butter, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
