I've seen tres leches cake in store bakeries, I've seen recipes for it and I've even seen it made on several cooking shows, but I've never tried it myself. I'm not sure how well it would go over with my family. My husband prefers pie to cake anyway, and I don't know about my mom. She might like it, or she might not.
The recipes don't look like they're difficult, which is certainly a plus, and one of these days, I may get up the gumption to try one. If no one in my family will eat it, I can always take it to work and the chow hounds there will consume it.
