Why it works: Mushroom and shallot are a kitchen classic. They rank in the top 4% of all ingredient pairs, and 1,982 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Mushroom Trimmings, Preserved for Fine Herbs
Ingredients
Directions
Prepare
Wash the mushroom trimmings and chop them finely, then press the chopped trimmings in a towel to remove moisture.
Chop shallots to equal one-eighth of the amount of mushroom trimmings and press them in a towel.
Cook and jar
Mix the mushroom trimmings and shallots in a saucepan with a piece of butter, then cook over medium heat for 10 minutes, stirring occasionally.
Let the mixture cool.
Pack the mixture into pint jars or glass jars and seal them tightly.
Boil the sealed jars in a hot water bath for 1 hour.

What each ingredient does
- Mushroom trimmings

- Shallots
- Add a mild sweetness and aromatic depth that complements the mushrooms.
- Butter
- Adds richness and carries flavor while the mushrooms cook in the saucepan.
The step that matters
Pressing the chopped trimmings and shallots in a towel. Mushrooms hold a lot of water. Removing moisture before cooking lets them brown and concentrate in flavor rather than steam, and reduces excess liquid in sealed jars.
