Hero method: lion's mane mushroom steak
Lion's mane mushroom 1 large mushroom
Garlic miso butter 7g
Lion seasoning 20g
Olive oil 7g, plus a little for the pan
Method:
Home-friendly pressing and marinating method
1. Slice the lion's mane mushroom into steaks around 1-1.5cm thick. Place them on a tray.
2. Brush both sides with the garlic miso butter.
3. Heat a large frying pan or cast-iron pan over a medium-high heat with a little olive oil.
4. Place the mushroom steaks into the hot pan. They may look quite thick and fluffy at first, but they will flatten as they cook.
5. Place a second clean pan directly on top of the mushroom steaks. Press down gently but firmly on the top pan. You want to squash the mushrooms slightly so they make good contact with the hot pan, but not crush them completely.
6. Keep the top pan in place for 3-5 minutes. This squeezes out excess moisture and gives the mushroom a firmer, steak-like texture. If the top pan is very light, carefully place a tin of beans or another heatproof weight inside it.
7. Remove the top pan, brush the mushrooms with a little more garlic miso butter, then flip them over.
8. Repeat the pressing process on the second side for another 3-5 minutes, until both sides are golden, browned and slightly crisp at the edges.
9. Lift the mushrooms out of the pan and leave them to cool slightly.
10. Mix the lion seasoning with the olive oil, then brush this over both sides of the mushroom steaks to marinate.
Safety note: Press gently at first, as the mushrooms release steam and liquid. If the pan smokes heavily, turn the heat down slightly. Use a pan that sits comfortably inside the bottom pan so it feels stable.
