咖啡里加点盐! 你们要是之前没这样做的做出来肯定会谢我. 当然推荐用Lavazza的咖啡豆.
随便查下网上是这样写的
Salt
Just like a pinch of salt can improve dessert recipes, a dash of it can upgrade your next pot of coffee. Salt can 'neutralize' some of the bitterness of coffee, leaving you with a smoother drink. Just pour a pinch (roughly 1/8 teaspoon) into your coffee grounds before brewing.
