My recipe uses 5 egg yolks, one whole egg there is not much beating. One can evaporated milk, one can condensed milk stir. Melt the sugar over low heat, then let it cool making a candy topping. Pour in the mixture, put the dish into a warm water bath to bake but it cooks for over an hour in the oven. It’s very tricky. I’m Cuban and there’s only two types of flan, great and gross. I’ve never had great flan in any restaurant or bakery. You know it’s good when you make it and people who hate flan are asking for seconds lol. There’s never leftovers.
