How to Prep Portobello Mushrooms
1. Rub the caps with a paper or cloth towel or use a vegetable brush to remove any dirt. (It is not necessary to peel cultivated mushrooms, such as portobellos, which grow in sterilized compost mixture.)
What You’ll Need:
2. Pull off any stems and save for soup stock.
Tip: Wiggle stem back and forth gently to avoid wasting excess mushroom.
3. If the caps have very dark gills, you may wish to remove them. Using a small spoon, paring knife or a serrated-edge grapefruit spoon, scrape off the gills and discard.
4. Use portobello caps whole or sliced or cut them in half and then slice. Cut them into 1/2-inch squares for chunky sauces, or use them as a receptacle for savory stuffing.
