If I look through the <a href="http://www.campbellsoup.ca/en/nutrition/nutrition_search.asp" title="Nutrition Search with Campbell Company of Canada">nutritional information</a> at Campbell’s, it appears that a serving of soup is about a cup (<a href="http://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=250+ml+in+cups" title="Google Search: 250 ml in cups">250 ml</a>).
No fixed plans. Not intent upon arriving.
