FAQ
Can I use different mushrooms?
Yes, cremini, shiitake, or oyster mushrooms work well. Adjust slicing thickness for different varieties and cooking times may vary slightly.
What if I don't have cornichons?
Regular dill pickles, capers, or chopped olives work as substitutes. Use same amount and dice finely for best texture in remoulade.
How long do leftovers keep?
Fried mushrooms stay fresh 2 days refrigerated but lose crispiness. Reheat in 400F oven for 5 minutes to restore some crunch.
