  • Step 1

    Pour the vegetable oil into a ramekin and add the cumin, paprika, oregano and sugar along with some salt and pepper and mix well. Brush the mushrooms on both sides. Marinate for at least an hour but preferably for a few hours.  

  • Step 2

    To install the grill plate, position it flat on top of the heating element and gently press down until it sits in place, then close the lid. 

  • Step 3

    While holding the smoke box lid open, use the pellet scoop to pour pellets into the smoke box until filled to the top. Then close smoke box lid. For Woodfire Flavour interaction, see pages 10-11 for further details. 

  • Step 4

    Turn dial to GRILL. Select WOODFIRE FLAVOUR. Set temperature to HI and set time to 12 minutes. Select START/STOP to begin preheating (IGN and preheating will take approx. 10 minutes). 

  • Step 5

    When unit beeps to signify it has preheated and “ADD FOOD” is displayed, open lid and place the mushrooms, cap side down onto the grill plate.  

  • Step 6

    When unit beeps and the display reads FLIP, open lid and use silicone-tipped tongs to flip the mushrooms. Close lid to continue cooking. Once cooking complete serve immediately.
