How to cook
Pour hot water in a pot to boil it faster, add a little salt to it. Once it's boiling, pour in the macaroni and boil until fully cooked.
Once boiled, cool with cold water and strain.
Pour mixture into a tray and place the hard butter on top. Put to bake in a preheated 356°F (180 °C) oven about 20-30 min. until the macaroni redden.
If you like you can take the tray out during baking and sprinkle with a few tbsp sugar, return to the oven to caramelize.
