The ABCs of Everyday Soup: The Weeknight Broth
If you grew up in a Cantonese household, the smell of this deeply savory broth simmering on the stove meant you were home. Old cucumber—recognizable by its heavily wrinkled, golden-brown skin—is a cultural staple used by grandmothers to soothe the body after a brutal day. Traditionally, this soup demands a three-hour stovetop vigil to coax the collagen out of the pork bones and the umami out of the dried seafood. But for a busy Tuesday night in an American kitchen, we can reverse-engineer those exact ancestral flavors in under an hour using a pressure cooker. The rules are unbending: never peel the cucumber, and aggressively blanch the bones to ensure a pristine, clear broth. It’s a flawless translation of heritage cooking, yielding a bowl that tastes exactly like the motherland.
Ingredients
- pork neck bones1 1/2 lb
- water8 cup
- old cucumber1 med
- carrot1 large
- sweet corn1 med
- dried cuttlefish15 g
- dried scallops3 large
- Chinese red dates6 med
- honey date1 med
- fresh ginger3 med
- dried goji berries1 tbsp
- kosher salt1 1/2 tsp
Method
- 01
Blanch the pork bones to ensure a clear broth.
Place the raw pork bones in a standard pot, cover with cold tap water, and bring to a rapid boil over high heat for five minutes. Dump the contents into a colander and vigorously rinse the bones under cold water, scrubbing away any coagulated gray foam or blood. This non-negotiable technique, called Chuen Shui, prevents a muddy, sour-tasting soup.
- 02
Extract the flavors under high pressure.
In the insert of an electric pressure cooker, combine the cleaned pork bones, old cucumber, carrot, corn, dried cuttlefish, scallops, red dates, honey date, and ginger. Pour in the water, secure the lid, and set the machine to High Pressure for 45 minutes. The high pressure exponentially accelerates the breakdown of collagen and extraction of umami.
- 03
Skim the fat from the finished broth.
Allow the pressure to release naturally for 15 minutes, then quick-release any remaining steam. Carefully remove the lid and use a spoon to skim off the excess oil that has pooled on the surface.
- 04
Steep the goji berries and season.
Stir in the dried goji berries and let them sit in the hot broth for five minutes. Never boil the goji berries, as they will turn the soup unpleasantly sour. Taste the broth and season with kosher salt before serving immediately.
Notes
Respect the old cucumber skin.
Never peel the cucumber. The tough skin prevents the flesh from dissolving into mush under extreme pressure and holds an immense amount of the nutritional value highly prized in traditional medicine.
The dried seafood umami bomb.
Adding dried cuttlefish and scallops to a pork soup might sound chaotic to a Western palate, but it is the pinnacle of Cantonese flavor construction. The synergy between the pork collagen and the glutamates in the seafood is what triggers that immediate, visceral nostalgia of a childhood kitchen.
