What is Berber Blend / How to make Roast Lamb with Berber Sp

While perusing the grocery store I came across a jar of spice called "Berber Blend" - I bought it thinking it would be a great WTF episode. When I got home, I found out that Berber refers to the indigenous people of North Africa, and this blend that I bought is a mixture of the commonly used spices in that region. It was recommended to use it on lamb, which is exactly what I did.
