While best used fresh - my ideal serving for cepes is to get really firm smaller ones, trim the ends and sear in a pan with olive oil then adding butter, minced garlic and parsley towards the end. These mushrooms are a great addition to risottos and meat jus for sauces. However, often you'll find you have found older cepe or just have too many and I find slicing them and freezing or dehydrating is the best way to reuse. I'm not a huge fan of the canned ones as they lose a lot of their texture. Making a dried mushroom powder to add to dishes for that extra umami flavor is also a great way to savor them year-round.
