Caramelize the sugar on a heavy-bottomed stainless steel pan. Once you?ve got the sugar caramelized to a nice golden amber, coat the bottom and a portion of the sides as well, with the caramel.
In a bowl, gently whisk the eggs. Then add the condensed milk and evaporated milk.
Whisk some more until the ingredients are well blended. Do not overmix to avoid bubbles.
Strain the mixture then transfer to a pan. Cover the pan with aluminum foil and place in a steamer.
Steam for 45-60 minutes, testing for doneness with a toothpick. Alternatively, you can cook your leche flan in the oven.
Place the pan on a water bath and bake at 350F. Test for doneness at 45 minutes. This may take a wee bit longer.
When it's done, let cool then chill in the refrigerator.
