Common Mistakes to Avoid

- Neglecting seasoning: Failing to season properly can result in bland flavors. Make sure to season with salt and pepper generously before baking.
- Not draining excess moisture: Waterlogged mushrooms can ruin the dish. Pat the mushroom caps dry with a paper towel before stuffing them.
- Skipping the lemon juice: Lemon juice adds brightness and balances the richness of the cheese and crab. Don’t omit it for enhanced flavor.
