Grandma Lurdes' Pudding Secret

Separate and strain the egg yolks into a bowl.

Add the strained eggs, sweetened condensed milk, and cow's milk to a blender or mixing container.

Prepare the flan mold (20 cm size, as per the video) by adding a little vinegar to the sides and the bottom.

Pour the prepared flan mixture into the caramelized mold.

Cover the mold with aluminum foil, ensuring the foil does not directly touch the flan batter.

Place the flan in a preheated oven at 482°F (250°C), preferably in a water bath (implied by the flan technique and cooking time).

After baking, remove the flan from the oven and let it cool completely before unmolding (it is best to refrigerate for 4 to 5 hours, or leave it overnight in the refrigerator).
