Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

What each ingredient does
- Butter
- Provides the rich fat and body that carries the sauce's flavour and smooth texture.
- Lemon juice
- Adds bright acidity that cuts through the richness of the butter.
The step that matters
Adding the lemon juice gradually. Acid added too quickly can make the butter separate or turn grainy. Adding the juice a little at a time while stirring lets the butter absorb it and keeps the sauce smooth and cohesive.
