Combo sauce , or Gombo sauce , is a traditional recipe very widespread in several countries in Central African and West, notably in the Central African Republic, Cameroon, Gabon and the Democratic Republic of Congo. It is a rich stew made from Gombo (or Okra), often accompanied by meat, fish or seafood, and served with starchy foods such as cassava or plantain. I have it that evening cooked with a mackerel.
If you prefer a thicker sauce, cook longer so the okra releases more mucilage. You can also add shrimp or a whole fish to the sauce for a richer seafood version.
You can also make this Gumbo with beef or chicken: in this case, first brown the meat in pieces in a little oil to brown it, then add it to the sauce while it cooks.
