We don't always love receiving words of wisdom from older generations. The years of having to listen to our parents may have traumatized us permantenly in that way. Sometimes though, these older folks have something good to say -- especially when it comes to food.
And when those older men and woman happen to be well-respected authors, then you really should trust what they have to say; they've worked hard to earn the respect of their written word. When you see what Voltaire had to say about ice cream, you'll quickly agree with us.
