In Japan it is rare to find what we would think of as a pumpkin. The giant orange vegetable used for Halloween is usually only found in Tokyo around October, sold in a few large stores as a gimmick--the Japanese don't use this pumpkin for cooking. Canned pumpkin is also rare and naturally, so is pumpkin pie. However, there is a species of pumpkin that is immensely popular (especially with the ladies), called 'kabocha'. The very sturdy outer shell is green (even when ripe) and the inside contains a very dense orange flesh with a small amount of pulp. Kabocha is naturally sweet and creamy when cooked. It is not watery at all and has the consistancy of mashed potatoes. Do not compare it to a yam...the texture is much creamier.
The Japanese like to barbeque thin slices of kabocha or use it for tempura. Another popular method of serving this pumpkin is to cube it and simmer it in a mixture of soy sauce, sugar and mirin. Occasionally a cream soup is made from kabocha, which is the method I am demonstrating today. I used the same soup base as I do for cream corn soup--a roux made of butter, milk and chicken stock. The cooked and blended kabocha is added near the end of cooking time, as well as sugar to taste (you don't need much!). This soup is delicious and creamy due to the vegetable itself. As a bonus it is a super source of Vitamin A. If you can find one at your asian grocery shop, I highly recommend it--it's a sure thing the ladies will like it! ^_^
