Then, using a small glass, press and spread the dough in the glass forming a hole in the center.
Next, in each one, add 1 tablespoon of strawberries cut into smaller pieces, the condensed milk and set aside.
In a large saucepan, add the eggs, the sugar, the cornstarch, the milk and stir until the cornstarch is completely dissolved.
Turn on the heat to medium-low and keep stirring until it becomes a smooth and even cream.
