Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potted Fish
Ingredients
Directions
Layer slices of herring or salmon in a jar, dusting each row with flour, white pepper, coarse sea salt, and small pieces of butter.
Cover the fish with vinegar.
Place the jar in a pan of boiling water and cover it closely.
Once cooked and cooled, pour melted lard over the fish to preserve.
