Tips for choosing fresh ingredients:
- Choose field crab: Choose live crabs that move quickly and have large, firm claws. Female crabs with shiny shells and large aprons often have a lot of roe, which helps the broth to be sweet, fatty, and have a distinctive aroma.
- Choose amaranth: Prioritize young amaranth with small stems, soft leaves, and bright green or purple color. Avoid vegetables that are bruised, wilted, or have signs of worms.
- Choose Malabar spinach: The leaves are thick, dark green, glossy and unbroken. The young bunches of herbs help the soup not be slimy when cooked and have a natural sweetness.
- Tips for adding flavor: You can add a few slices of squash or young gourd to increase the freshness, making the crab and amaranth soup more sweet and attractive.
