Mix Egg Yolks and Starch: In a separate bowl, whisk together the egg yolks and potato starch until smooth.
Add Milk Gradually: Slowly pour in the milk, whisking continuously to prevent lumps, until fully combined.
4. Combine the Ingredients:
Add Milk Mixture to Bananas: Pour the milk and egg yolk mixture into the saucepan with the bananas. Stir constantly until the mixture thickens and begins to boil.
5. Finish the Dessert:
Cool Slightly: Remove the saucepan from the heat and let the mixture cool slightly.
Fold in Cream: Once cooled a bit, gently fold in the fresh cream until the dessert reaches a smooth, creamy consistency.
6. Chill and Serve:
Refrigerate: Transfer the mixture to serving dishes and refrigerate for at least 2 hours.
Serve: Serve the dessert cold, optionally garnished with fresh fruit, whipped cream, or a sprinkle of cinnamon or nutmeg.
