Start by washing and halving strawberries.
Smoothly blend fresh strawberries in a blender.
Strain the blended strawberries into a bowl and set aside.
In a bowl mix the granulated sugar and egg yolks together.
Add cornstarch to the mixture and whisk again.
Simmer milk in a big saucepan.
The heat should be turned off and some milk should be whisked into the bowl.
While whisking continuously, turn on the heat again and simmer the mixture.
Whisk the mixture until it thickens.
Add vanilla extract and continue whisking.
Mix the strawberry puree into the pot.
Add strawberry paste or red food color and mix again.
Turn off the heat when the custard is creamy.
Allow the custard to cool in a bowl.
Enjoy it!
