Hints and tips
• Gourmet waxy potatoes to be used for this recipe, such as perlas, jersey benne, Dutch cream, sebago, desiree or Nadine.
• The potatoes can be cooked for 15 minutes and then chilled until ready to use. To serve, cook for an additional 15 minutes at 200°C on Fan Plus until crispy.
• Mushroom powder can be made from grinding down store-bought dried mushrooms, or by dehydrating your own in the oven on Conventional at 80°C for 2–4 hours, then grind in a spice grinder.
• When frying the mushrooms, use the largest pan to encourage browning or cook in two batches.
• Potato starch helps the potatoes to stick together, and is also great for hash browns. If not available, cornflour can be used instead.
• For the pickled mushrooms, use a wide variety of the most interesting ones you can find.
• If pickled mushrooms cannot be prepared a day in advance, pickle for a minimum of 2 hours.
• Leftover mushroom puree can be used as a spread, or a dip.
