Put the cashews in a bowl and pour boiling water on them to cover them. Soak for an hour.
Put also the raisins in a bowl and cover with water. The water for the raisins doesn't have to be boiling. Soak the raisins only for 45 minutes and start to work on the crust while the cashews are still waiting for their turn.
Drain the raisins well. Put them in a blender and blend until they form a ball. Set aside.
Put the almonds in the blender (no need to wash it after the raisins) and blend them into a coarse flour. Add the raisin mash and coconut milk and blend to a sticky mix. If your blender is not powerful enough, you can mix these three ingredients also in a bowl.
Press the crust evenly into the bottom of your pan with your fingers and put it in a freezer.
Measure all the ingredients for the filling in the blender (washed) and let it run for a couple of minutes until the filling is smooth and creamy and there are no cashew bits left.
Take the pan out of the freezer and pour the cake filling on the crust. Put the cake back in the freezer and let it chill for at least 4 hours or until it's completely set.
Prepare the lingonberry layer. Crush the berries a little with a fork to get some juices out. Add chia seeds and spices. Put the jam in a fridge for at least half an hour to form a jam.
Take the cake from the freezer at least 15 minutes before serving. Pop it out from the pan and spoon the lingonberry jam on it before cutting.
