 - 1/4 cup chopped peeled fresh ginger (from about 3-inch-long piece)

Preparation
For spice mix:
Toast all ingredients in heavy medium skillet over  medium heat until spices darken slightly in color and start to pop,  stirring occasionally, about 7 minutes. Cool in skillet. Transfer to  spice mill and grind finely.
For soup:
Heat oil in heavy large pot over medium-high heat. Add  celery, onion/shallots, and carrots. Sauté until vegetables soften slightly,  about 8 minutes. Add ginger and garlic and sauté 3 minutes. Add bell  peppers and fennel. Stir 2 minutes to coat. Add tomatoes; cook until  tomatoes soften and break down, stirring often, about 8 minutes. Add  broth and bring soup to boil. Reduce heat to medium; simmer until all  vegetables are tender, about 25 minutes. Add ground spice mix; return  soup to boil. Remove from heat; cover and steep 20 minutes.
Place coarse sieve over large bowl. Working with 2 cups  at a time, strain soup into bowl, pressing liquid and most of solids  through sieve. Season soup to taste with hot pepper sauce, salt, and  pepper. Refrigerate soup until cold, at least 3 hours. (Can be made 1  day ahead. Cover and keep refrigerated.)
Ladle soup into 8 shallow bowls. Divide crabmeat among  bowls. Garnish with radish slices and chives.
