Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,036 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
The recipe
Ingredients
Contains: milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Remove the salt from the salted cod.
In a large pot, add the fish and cover it with water. Heat until just before boiling, then remove from heat and cover.
In a separate pan, melt the butter, add flour, water, and a little salt. Taste and adjust seasoning with salt and pepper.
Return the sauce to low heat and stir until it thickens.
Finely chop the parsley and mix with a little glaze and lemon juice. Taste the sauce and adjust color with thick cream if too brown.
Remove skin and bones from the fish and gently mix it into the sauce.
Serve in a vol-au-vent or deep dish with puff pastry croutons.
