Juice 6 limes and strain the juice into a bowl to ensure there are no seeds.

Meanwhile, spread a little butter over the base of a dish. In a blender, grind half a package of Maria cookies. Once ground, place the cookie crumbs in the dish with the butter.

In the blender, mix the evaporated milk, sweetened condensed milk, and lime juice. Blend until you have a creamy mixture.

In the dish, layer cookies and then a layer of the creamy mixture, spreading it until the cookies are covered. Repeat the layering (cookies + mixture) until the dish is full. Once full, place the dish in the freezer for one hour, then transfer it to the refrigerator.
