By Matt Rosenberg. A nations economy can be divided into various sectors to define the proportion of the population engaged in the activity sector. This categorization is seen as a continuum of distance from the natural environment.
Chow-Chow (or Chow-Chow Relish) is made from chopped green tomatoes (and sometimes red tomatoes), cabbage, mustard seed or powder, onions, hot peppers, sweet peppers, and vinegar.
So I continued my mission online and after looking at as many Picadilly recipes as I could find (this is a surprisingly uncommon recipe), I came up with what I think is a pretty close match to the original relish I had eaten.
