Whisk the cream cheese until soft. Mix in the corn flour with the sugar and combine well. Add into the cream cheese and whisk until smooth. Scrape down the sides a couple of times to make sure all the cream cheese is whisked in.
Beat the eggs lightly then add to the cream cheese gradually in 2-3 parts, mixing well with each addition *do not over-mix* Switch to mixing by hand to remove the air bubbles. Set aside and start on the matcha cream.
Add 20g matcha powder to 75ml hot water ~80C. Mix till the matcha is fully incorporated. Add in the heavy cream to the matcha and mix well. The matcha cream will be rather thick and clumpy at this stage.
Once well mixed, microwave the matcha cream for 40 sec and stir well. This is to make the matcha cream smoother, more fluid, and also to bring out the flavor of the matcha. Stir to cool the matcha cream till it is only slightly warm to the touch, then add it to the cream cheese.
Gently mix the two with a whisk till combined. To remove any lumps, sieve the cream cheese batter into a lined 6-inch springform baking tin.
Bake at 220C for 30 min. Remove from the oven. The top will be brown and charred but the cheesecake should still be wobbly. Cool completely, then chill in the fridge for 4 hours or overnight to set.
Just before serving, remove from the fridge and un-mould the matcha cheese cake. Gently remove the parchment from the sides. Spread a generous tablespoon of pistachio cream on top and decorate with fresh raspberries and crushed pistachios all around. Serve chilled and enjoy.
