Choose the substitute based on recipe needs: dried options for umami and texture, fresh for texture, or powders/broth for flavor enhancement.
If using dried mushrooms, rehydrate in hot water for 20-30 minutes then drain and squeeze excess water.
Measure the substitutes using the recommended ratios compared to porcini mushroom weight or volume.
Sauté fresh mushrooms to release moisture and flavor before adding to the dish.
Add mushroom powder or broth during cooking to boost savory depth without adding texture.
