Moo's Cream of Ginger-Lemongrass Soup

I love this soup. It is light and flavorful. It's also got a little zip to it. Thank the chili bean paste for giving this soup that little something extra. Moo loved lemongrass and she liked to mix delicate flavors with a little spice. Dare it say it...chili bean paste was her "Bam!"

2 T olive oil
1 T fresh ginger, finely chopped
2 T lemongrass, finely chopped
2 T shallots, finely chopped
1/2 cup yellow onions, finely chopped
2 cups fresh corn
4 cups chicken stock (for vegan/vegetarian version use vegetable broth)
Salt and pepper to taste
2 tsp. sugar
1/2 cup half and half (vegan replace with a soy creamer)
2 tsp. chili bean paste
Coriander leaves for garnish

Heat olive oil in pot, add ginger, lemongrass, shallots and onions. Cook on low heat for 2 minutes. Add corn and cook for another minute. Add stock and bring to a simmer. Cook on low heat for about 5 minutes, add salt and pepper, then sugar and half and half. Remove pot from heat and cool to room temperature. When ready to serve, stir to blend ingredients and return pot to heat. Ladle into soup bowls add a dot of chili bean paste to top and swirl it with a knife to create a pleasing pattern. Garnish with coriander.
