Charcoal is a common denominator

 
Charcoal is common both in the US and the Congo.  But it is used differently.

Fathers and men in the US is generally allow to cook outside.  They love to grill for the fun of it.  They grill and cook with either charcoal or gas.

In urban areas of Congo, families cook outside most days.  They use charcoal most of the time.  They are not grilling for fun.  And women and mothers are the cooks.
