Crack the eggs into a bowl and stir gently. Then, pour the sweetened condensed milk into a pot, add 1 cup of boiling water, and stir well. Add the whole milk and 2 tablespoons of sugar, adjusting to your family's taste. Heat the milk mixture, then pour it into the bowl with the eggs, stirring gently. Strain the mixture through a sieve to make it smooth.

Put the sugar and a little water in a pan and heat until the sugar caramelizes to a golden brown. Add a bit more water and turn off the heat.

Pour the caramel into a baking mold, just a thin layer. Then pour the strained mixture from step 1 into the mold, cover, and steam for about 35 minutes.

Test with a toothpick; if it comes out clean, the flan is done. Let it cool and store in the refrigerator to enjoy later.
