I don’t know if in your country you can easily find ceps and if they are affordable. In France, ceps season in in Autumn, and they are really expensive. However, we can find dried ceps all year long. Jars of dried ceps might seem a budget but you only need a small quantity to flavor a whole dish. If you do a bit of math and look at the cost per serve, you’ll see that this dish is not that expensive.
How to make a perfect French purée with a twist
In this recipe, I use 40 grams (1,4 once) of dried ceps, which is only 10 grams per person. The idea to the recipe is to prepare a smooth purée (or more lumpy mashed potatoes if this is what you prefer) in which you will add ceps. The first thing to do is to rehydrate mushrooms in milk for at least 1 hour. Don’t throw away the rehydratation liquid when you drain mushrooms as you will use it in the purée. This milk gets all the flavours of ceps. I choose to briefly sauté ceps in butter, add the drained milk to reduce a bit, then mix to get a smooth cep purée. Finally this is simply added when you mash potatoes, with more butter, cream and milk according to the texture and smoothness you wish.
