Add the 2 milks to the eggs, mixing with a hand blender if you have one.
Now you’ll need a glass mold to prepare the caramel. In a small fry pan at medium temperature, pour the sugar and 4-5 drops of lime juice. Wet your hand and let 4-5 drops of water onto the pan. Move the pan around until the sugar is totally melted and a deep golden color, not a brownish color, which means the sugar burned.
Pour the caramel into the mold and cover all its surface. Once the sugar settles and dries in the mold, add the mixture of eggs and the two milks.
Now it’s ready for the oven. But not so fast. You’ll need to set up a water bath (bain Marie) by placing the mold inside another mold that will cover up to 3/4 of the sides of the egg/milk mixture.
Leave the double boiler in the oven at 350ºF for 45 minutes.
Check if it's ready by inserting a knife between the mold and the flan. If it slides out clean, the flan is done.
Once the mold has cooled, separate the flan from the sides of the mold with a knife.
Place it in the fridge or freezer so it can cool.
Flip the cold flan onto a large serving tray. Decorate with coconut flakes.
