Where did the term Dutch Oven originate?

Answer 1

I found this on Yahoo answers where Ross answered the same question:

The history of the term 'Dutch Oven' to mean a bad smell is thought to be this. In the late 17th century trading resumed between Holland and Great Britain between the 3rd and 4th Anglo Dutch wars. A trader believed to have been known as De Vries carried a shipment of many different commodities across the channel to the UK. The shipment contained amongst other things, a consignment of Dutch ovens - a popular cast iron/ceramic cooking vessel of the time and a load of 'Spirit of Hartshorn', known as ammonia today, which had many uses which included for cleaning and as a fertiliser.

De Vries ship met with poor weather on the trip and the ovens became contaminated by the ammonia. Once the ovens were distributed around the capital people found the stench of the ammonia which had impregnated the ovens to be intolerable. Due to the tensions from the wars it was common at this time for the British to use anything Dutch as a term of belittlement (see 'Dutch Courage', 'Going Dutch' etc) It then became popular to refer to a noxious smell as 'Smelling like a Dutch oven'.

First record of the term being used as slander was found in the English one sheet newspaper 'The Daily Courant' in 1705.

It seems that the act of enclosing someone in a small 'oven like' space such as a duvet with a bad smell such as flatulence has now become the current usage of the term 'Dutch Oven'.
