To Preserve Mushrooms
Ingredients
Directions
Prepare
Peel the mushrooms, put them into cold water with a little lemon juice; take them out and dry them very carefully in a cloth.
Add 3 oz. of butter, pepper, salt to taste, juice of 1 lemon, and clarified butter to each quart of mushrooms.
Cook
Put the butter into a stewpan capable of holding the mushrooms; when it is melted, add the mushrooms, lemon juice, and a seasoning of pepper and salt; draw them down over a slow fire, and let them remain until their liquor is boiled away and they have become quite dry, but be careful not to allow them to stick to the bottom of the stewpan.
Store and serve
When done, put them into pots and pour over the top clarified butter.
If wanted for immediate use, they will keep good a few days without being covered over.
To re-warm them, put the mushrooms into a stewpan, strain the butter from them, and they will be ready for use.

What each ingredient does
- Mushrooms (in the method)
- Main ingredient that softens and releases liquor, then concentrates as it dries in butter.
- Butter (in the method)
- Carries flavor and richness, and seals the mushrooms when poured over them for keeping.
- Lemon
- Adds acidity that brightens the mushrooms and helps keep their color light.
The step that matters
Drawing down over a slow fire. Gentle heat lets the mushroom liquor evaporate slowly so the mushrooms dry without scorching. Too much heat or too little stirring makes them stick to the pan and burn.
