Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and 25,843 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Potage Aux Petits Pois
Ingredients
Directions
Layer onions in a pot and add small slices of veal and various herbs.
Pour in stock and let it stew gently until it develops a good color.
In a separate pan, fry a little bacon with parsley.
Add green peas to the bacon and stew until tender.
Pound the peas in a mortar and mix them into the soup with the veal.
Once thickened, remove the veal to serve with another sauce.
Pass the soup through a fine sieve until smooth.
It should be as thick as cream; add a pinch of powdered sugar to taste.
