Our family enjoyed this hard cheese which, although stinky (like a teenage boy's feet in the summer), had a rich creamy flavor. The "tres leches" refers to the different types of milk involved: sheep, goat and cow. If you told me it takes no fewer than three animals to make a cheese so delicious, I'd have no choice but to believe you.
