About this recipe: So delicious! This classic - also known as creme caramel - is a rich and creamy but not too heavy custard on a layer of caramelised sugar, baked in a water bath and chilled. The secret is long cooking (1 hour) at relatively low temperature (140 degrees C) and very careful caramelising of the sugar! Make sure that the melted sugar remains light brown when you place it into the ramekins. If it's too dark it gets too hard and any flan will taste too strong in this way (or even will taste slightly burnt).
