I love puree because you can do it in many ways. This time we are going to do a mashed potato with apple and onion, which you will like very much, for its texture and its flavor. You'll see, although it may not seem like it, apple and onion get along very well.
You can use the variety of apple that you like the most. With the Golden It looks great but do not hesitate to use the variety you have at home.
We are going to cook all the ingredients in milk. When they are well cooked, we will pass them through a food mill or we will integrate them all with a simple fork.
