Why Do People Like Súp Cua Trứng

There are a few reasons why súp cua trứng (crab and egg soup) is a popular dish in Vietnam:

  • Flavor – The broth has a rich, savory seafood flavor from the crab meat and shells. The egg adds creaminess and richness. The combination of crab, egg, and broth is very tasty.
  • Texture – The soft, silky egg contrasts nicely with the crab meat. The additions of crunchy bean sprouts and fresh herbs like cilantro and green onions also provide texture.
  • Nutritious – Crab is a lean source of protein. Eggs are also protein-rich and contain vitamins and minerals. The broth is nourishing as well. So the soup can be a healthy and satisfying meal.
  • Cooling – Vietnamese soups are considered cooling foods, thought to balance out hot and spicy foods. Súp cua trứng is a good choice during hot weather or with spicy dishes.
  • Versatile – The soup can be eaten on its own or with rice or bread. It works for any meal too – breakfast, lunch or dinner.
  • Comforting – Warm broth, soft egg, and fresh herbs are comforting to eat. The soup has a soothing, feel-good factor.
  • Easy to make – While some versions are complex, basic súp cua trứng has simple ingredients and preparation suitable for everyday meals.

Ingredients For Súp Cua Trứng

For the crab meat, fresh lump or jumbo lump crab is ideal. It has the best flavor and texture. However, canned crab meat works well too – just make sure to drain it thoroughly before using.

The broth is traditionally made using chicken broth, though seafood or vegetarian broth also pair nicely with the crab. Light, clear broths work best to keep the flavor clean and let the crab shine.

Other ingredients that enhance the flavor include:

  • Ginger – adds warmth and brightness
  • Garlic – provides aromatic foundation
  • Green onions – contributes fresh, grassy notes
  • Soy sauce – builds savory umami flavors
  • Rice wine vinegar – brings mild acidity to balance flavors
  • Salt and white pepper – season to taste

Equipment For Cooking Soup

Crab Egg Drop Soup comes together quickly, so you don’t need much special equipment.

  • A large pot with high sides is ideal to contain splattering broth when adding the egg drops. A 4-quart stockpot or Dutch oven works perfectly.
  • A slotted spoon or mesh strainer makes it easy to remove the crab meat from the broth as it simmers.
  • A whisk or fork is useful for gently drizzling the beaten egg into the broth.

Prepare Ingredients To Cook Soup

If using fresh crab, remove the meat from the shells first. Give the shells a rough chop and simmer in the broth for 30 minutes to infuse flavor. Discard shells before adding the crab meat.

For canned crab, simply drain it well in a colander and pick through the meat to remove any stray shell fragments.

Bring the broth to a bare simmer in a pot. The gentle heat helps the egg drops form nicely. Boiling broth can cause the egg to overcook and turn rubbery.

Beat the eggs just until blended, without whipping in air. You want a thin, liquid consistency to form elegant drops in the soup. Err on the less whipped side.

How To Make Súp Cua Trứng?

There are a few tricks to getting perfect egg drops:

  • Use eggs straight from the fridge for the best results. Cold eggs hold their shape better when hitting the hot broth.
  • Gently drizzle the eggs into the simmering broth in a thin stream. Don’t dump in big blobs.
  • Stir the soup in a circular direction after adding the egg to keep the drops separated.
  • Let the drops cook 1-2 minutes until set but still soft and pillowy.

To prevent overcooking the crab, add it during the last 3-4 minutes of simmering. This warms it through without making it tough. Add soy sauce, vinegar, and other seasonings gradually. Taste frequently and adjust until the flavors pop. The broth should taste balanced, savory, and full-bodied.

Serving Súp Cua Trứng

Crab Egg Drop Soup tastes wonderful piping hot, at about 145°F. The heat allows the flavors to shine and the egg drops to stay silky.

Garnish with a sprinkle of green onions and a dash of white pepper. Both provide color and reinforce the soup’s aromatic qualities.

Leftovers will keep 3-4 days refrigerated. The egg drops may weep a bit, but the flavors continue improving. Gently reheat leftovers on the stovetop, stirring often.
