Covid-19 Cooking: Duxelles

On the thirty-first day of Lockdown in France (Confinement Jour 31), I made duxelles which is a fairly straightforward technique of intensifying mushroom flavour by lessening the moisture content, allowing not only for various uses like pizza topping, pasta adornment, soup and stew enrichment among others, but also for freezing where, because of their reduced state, they won't take up much space. The most important aspect is that the texture doesn't become leathery and tough. You want intense flavour, but tender tidbits at the same time. If most of the liquid already is wrung from them before being sauteed and they are cooked in a large, shallow skillet, the duxelles will be subjected to drying heat for a much shorter time therefore remaining soft despite containing much less moisture.


Ingredients
makes 500 ml/a little over 2 American cups (recipe can be halved)

  • Mushrooms, fresh, 1 kg/2.2 lbs (I chose white button mushrooms, but any edible ones, wild or cultivated, can be used though the taste will vary from mild to strong depending on the variety)
  • Butter, sweet, 3 T
  • Salt, table, 1/2 tsp

As demonstrated by the above list of only three ingredients, this version is the most simple available among numerous recipes. In our household, duxelles is mainly used for pizza topping therefore the plainest form will be more compatible with the garlicky, herb-enhanced tomato sauce and the well-seasoned, often red-wine-enriched Toulouse sausages which also go onto the crust. However, if you desire racier versions, be rest assured they exist with various additions such as garlic, onions, cream, herbs, and booze. Either clean the mushrooms with a soft bristled brush or with a dry paper towel. Slice and then coarsely chop which is just the right size for pizza topping. A finer mince could be more suitable for other dishes.

Drap an old tea towel/dish cloth over a large bowl, pressing it to conform to the bowl's inner contours. Put the amount of chopped mushrooms that can easily fit once the towel is pulled around the mass and twisted closed. Old tea towel you say? Old enough that you don't mind it getting stained, but not so worn and thin that it will tear during the vigorous wringing process.


Squeeze by twisting tighter and tighter and also by massaging the 'bag' with your hands. At first not much liquid will ooze out. After a while, more and more will. Stop when most of the liquid is either squeezed out or you are tired (my preference!). Repeat until all the mushrooms are done. The mushroom liquid is quite plentiful. I couldn't find any information regarding if it could be used in other recipes or if it could be frozen. I am guessing if the raw mushroom liquid is used almost immediately as in a veggie smoothie, than it probably will be okay. Melt the butter over medium high heat in the largest, most shallow skillet you have or work in smaller batches if you only have small/medium sized pans. Add mushrooms and salt. Saute, while stirring frequently, for about five to eight minutes or until the duxelles no longer clump together, are slightly golden, and greatly reduced in volume. Don't mistake their being glazed with butter as moisture.


They then can be portioned and once cooled, popped into the freezer or kept for several days in the fridge.


Though the photo (I forgot to take one of a pizza with duxelles!) below shows how I used to strew a homemade pizza with commercially packaged, pre-sliced, frozen mushrooms which were then thawed before sauteing and added to the yet-to-be baked pie, I ask you to imagine how it would look instead with a dense sprinkling of duxelles applied before baking. Here's a clue: its appearence was charming. Additionally the flavour, texture, and aroma were way up there.


À la prochaine!
