Pastillas de leche literally means milk bars, pills, or tablets. I'd go with the bars, as in chocolate bars They are teeny tiny, usually less than 1 inch long and ½ inch thick, made with fresh milk, sugar, a little butter, and powdered milk, and optional natural fruit flavoring such as purple yam (ube) and jackfruit. The original candies were made with carabao's (water buffalo) milk which has a higher fat content than cow's milk. I made it a few times before. This time I ended up making 3 batches because the first was a complete fail although I rescued it and made it into milk caramel spread. The second one is plain milk and I added Milo malt drink powder into the third batch.
