Is it recommended to start with milk when there are various types of food on the table, and has a hadith been reported concerning that, and if so, what is its text?

There is no hadith indicating that it is Sunnah for one who is eating to begin by drinking milk if there are several types of food available. However, there are ahadith that explain etiquettes related to drinking milk, such as rinsing the mouth after drinking it due to its fattiness, and saying, "O Allah, bless us in it and grant us more of it," when drinking it, because it suffices as both food and drink.
