Tips for Success
- Pick even sizes. Mushrooms the same size bake at the same rate.
- Don't rinse them. Wipe with a damp towel so they don't soak up water.
- Pipe the filling. A zip top bag with the corner snipped makes stuffing fast and neat.
- Make ahead. Stuff, cover and chill for up to 1 day, then add 3 to 5 minutes to the bake.
- Add crab or sausage. Fold in 1/2 cup lump crab or cooked sausage for a heartier bite.
- At our table. Max calls these little cheese cups, and they disappear before the steaks are done.
