Growing up, I watched my mom make crab asparagus soup on special occasions or large family gatherings. White asparagus is expensive in Vietnam and since asparagus is not native to Vietnam, many people believe this dish was influenced by the French.
Each family has their own rendition of this classic dish. Some forgo the white asparagus for green asparagus or enoki mushrooms. What sets this crab asparagus soup apart from others is the addition of pureed corn juice.
The corn juice adds a subtle sweetness and flavor to the soup which allows the delicate white asparagus and crab meat to shine through.
Please let me know if you have any questions.
