Dalmatian Rub is simply equal parts salt and pepper; the color is black and white just like the color of Dalmatian dog. This is a common seasoning for beef when grilling and smoking.
Think fine grind for shorter cooks like grilling steaks and hamburgers and a coarse grind when smoking cuts like beef brisket.
