Fredrick the Great of Prussia was very, very keen for the Germans to adopt the potato and to eat it, because he realized that if you had two sources of carbohydrate, wheat and potatoes, you get less price volatility in bread.
Fridrich Veliki Pruski bio je vrlo, vrlo dosljedan kako bi Nijemce privolio da prihvate krumpir i da ga jedu. Shvatio je da, ukoliko imate dva izvora ugljikohidrata, žitarice i krumpir, manje će se mijenjati cijena kruha.
