Century Egg & Pork Congee (IDDSI Level 3)

IDDSI Level 3 (Liquidised) | 35 minutes | Easy

Century egg and lean pork congee (皮蛋瘦肉粥, pei dan sau yuk juk) is one of Hong Kong’s most deeply beloved breakfast dishes — a slow-cooked, silky rice porridge enriched with the distinctive savoury depth of century egg and the gentle sweetness of pork. It appears on the menu of every cha chaan teng, dim sum restaurant and hospital canteen, and is traditionally offered to the sick and recovering as a restorative comfort food. The traditional dish contains whole slices of century egg and shredded pork, which do not meet IDDSI Level 3 requirements. This adaptation blends the entire bowl into a smooth, uniform liquidised texture, retaining all the flavour and aroma of the original while ensuring safe swallowing compliance.

Ingredients (2 servings)

• 100g white rice (soaked 30 minutes, drained)
• 1500ml water or chicken stock
• 100g lean pork (very finely minced)
• 2 century eggs (shelled, cut into small pieces)
• 3 slices fresh ginger
• Salt to taste
• White pepper to taste
• A few drops sesame oil (for finishing)
• Spring onion, finely chopped (optional — only if the resident can safely manage soft solids)

Method

1. Place soaked rice in a pot with chicken stock (or water) and ginger slices. Bring to a boil over high heat, then reduce to low, cover, and simmer for 25–30 minutes until the rice grains have fully burst and the congee is thick and smooth.
2. Season the minced pork with a small pinch of salt and white pepper; stir into the congee and cook over low heat, stirring to break up any clumps, until the pork is fully cooked through.
3. Add the century egg pieces; stir gently and cook for a further 3 minutes so the flavour infuses the congee base.
4. Remove and discard the ginger slices. Adjust seasoning with salt and white pepper.
5. Transfer the entire congee to a blender. Blend for 45–60 seconds until completely smooth and uniformly liquid. If the texture is too thick, add a small amount of hot water and blend again.
6. Strain through a fine-mesh sieve if needed (optional, for maximum smoothness). Stir in sesame oil.
7. Serve immediately. Garnish with spring onion only if the resident can safely manage soft solid toppings.

Texture Test

IDDSI Level 3 (Liquidised) confirmation: Using a 10ml needleless syringe, draw up the blended congee — flow should reach 8–10ml within 10 seconds. When poured from a spoon, the liquid should flow in a slow, continuous stream (not drip, not separate into layers). Fork test: the liquid should flow through the tines leaving no solid residue.

Particle-free confirmation: After blending, there should be no visible pork particles, rice grains or century egg pieces. If particles remain, blend for a further 30 seconds and re-test.

Safety Notes

⚠️ Full blending is mandatory — traditional century egg and pork congee contains whole egg slices and shredded meat, which do not meet Level 3 requirements. The entire dish must be blended to a uniform liquid texture before serving.

⚠️ Century egg alkalinity — century eggs are alkaline (pH ~9–11) and may cause mild digestive sensitivity in some elderly residents. Limit to half an egg per serving (already diluted within the blended congee) and monitor tolerance.

⚠️ Sodium content — century eggs are high in sodium (approximately 400mg per egg); for residents with hypertension or fluid restrictions, use only one egg per batch and avoid adding extra salt.

⚠️ Temperature check — blended congee retains heat well and may be very hot at the centre despite a cooler surface. Verify that serving temperature is between 40–50°C before offering to residents.

Sourcing in Hong Kong

• Century eggs: Available at all wet markets and major supermarkets (PARKnSHOP, Wellcome); select eggs with intact shells and a clear, firm, translucent dark egg white; avoid any with cracked shells or off odour
• Lean pork: Wet market pork stalls — request the vendor to mince pork leg or tenderloin very finely; pre-minced pork is also available in supermarket chilled sections
• White rice: Jasmine rice (絲苗米) produces a smoother congee that blends more easily than short-grain varieties

Nutrition

Approximately 220 kcal per serving, 14g protein, 6g fat, 28g carbohydrate. Lean pork provides complete animal protein and iron, supporting muscle maintenance and anaemia prevention in elderly residents. Century eggs contribute zinc and modest iron, but are relatively high in sodium — relevant for residents with cardiovascular or renal concerns. The rice-based congee provides easily digestible complex carbohydrate, appropriate as a morning staple for residents with reduced digestive capacity.

Cultural Note

Century egg and pork congee occupies a unique place in Hong Kong food culture: it is at once a daily breakfast item sold at every cha chaan teng and a deeply personal comfort food offered to the unwell, the recovering, and the weary. The combination of umami-rich century egg and mild sweet pork produces a complex, warming flavour that is intimately familiar to most elderly Hong Kong residents. By blending the dish to IDDSI Level 3, this adaptation makes it possible for residents with dysphagia to experience that same warmth and familiarity in a form that is safe, dignified, and flavourful — sharing in the morning ritual that connects them to decades of Hong Kong food memory.
