So when you look straight up, the light passes through enough of the atmosphere, that you see mostly blue. But on the horizon, there is a lot more of the atmosphere, so blue scatters a LOT more and is then mostly lost. The reds and yellow pass straight through, and that is what you see.
Salami is a type of cured sausage consisting of fermented and air-dried meat, typically beef or pork. Historically, salami was popular among southern and central European peasants because it stores at room temperature for up to 40 days once cut, supplementing a potentially meager or inconsistent supply of fresh meat.
Bresaola is a great cured meat. It isn't made from pork, which is uncommon as far as salumi go; it is made from beef, or also, quite commonly in Italy, horse or donkey. Basically a very lean piece of meat (most commonly beef, especially if bought commercially) is salt cured with spices, then dried. Sliced thin it makes a superb antipasto when drizzled with a mixture of oil, lemon juice and black pepper, it great in a sandwich, and is delicious just eaten out of hand.
