Súp Măng Cua [Vietnamese Wedding Soup]

Súp Măng Cua [Vietnamese Wedding Soup]

Asparagus is grown in central and north Vietnam. And is not a common vegetable my family cooked with in Vietnam. However, we do love asparagus in our Diaspora communities. Most will identity this soups as Vietnamese Wedding Soup because it’s the soup everyone has at their Vietnamese wedding. This is my father’s version. California’s Dungeness crab season is very hostile. In these recent decades, it has seem to become more unstable. Between the California Department of Fish and Wild Life, And the National Oceanic and Atmospheric Administration, they will shut the crab fishing season down for a number of reasons; humpback whales breeding waters where crabs are fished; toxic algal bloom from global warming. Thus, adding to the preciousness of Dungeness crab.
