First, add a bit of milk to the cornstarch/corn flour and blend well. Once mixed, add the remaining milk.
To this homogenous mixture, add the lightly beaten egg and cream. Whisk well.
Once blended well, pour this mixture into a saucepan and constantly stir over low heat until the custard thickens. DO NOTBOIL this mixture since the custard might start to curdle.
Add, while stirring, the ground almonds/almond meal, sugar, and vanilla essence.
Once desired consistency is obtained, take off the heat and leave to cool.
Serve warm or chilled as desired.
