Why it works: Parsley and lemon 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 ↓
Fish
Ingredients
Directions
Clean the fish under running water.
Rub the fish with coarse sea salt and scrape with a knife.
Scale the fish using the back of a knife.
Skin the fish from head to tail, or tail to head for flat fish, using a knife for plaice.
Keep a fin on the fish while boiling to check doneness, or use a skewer near the bone.
Add a spoonful of vinegar to the boiling water for firm and tender fish.
Add a pinch of bicarbonate of soda when boiling salmon for a beautiful red color.
Soak salt fish in sour milk to freshen it quickly.
Scour the cooking pan with soda water after use, then rub with butter to remove fish odor.
Add a little vinegar to the pan after frying fish or onions to eliminate the smell.
Season bread crumbs with salt, pepper, and chopped parsley before using for fish fillets.
Lift fried items out of boiling fat three or four times during cooking to make them light and puffed up.
Salt the boiling water with one tablespoon of salt per gallon.
Add lemon juice to white fish for improved flavor.
