Cream of Corn Soup (Enriched) | IDDSI Level 4 Care Food Recipe

IDDSI Level 4 | 35 minutes | Easy

Ingredients (2 servings)

• 300g corn kernels (fresh corn cut from the cob, or canned whole kernel corn, well drained)
• 1/4 medium onion (finely chopped)
• 15g unsalted butter or 1 tablespoon olive oil
• 400ml low-sodium vegetable or chicken stock
• 200ml full-fat milk
• 50ml light cream (single cream)
• A pinch of fine salt
• A pinch of white pepper
• 1 tablespoon cornstarch (if needed to adjust consistency)

Optional Fortification (to increase energy and protein)

• 2 tablespoons full-fat milk powder (adds approximately 40 kcal per tablespoon)
• 15g cream cheese (adds richness, smoothness, and additional energy)

Sourcing in Hong Kong

Fresh corn is available at supermarkets and wet markets — choose cobs with plump, golden kernels. Canned whole kernel corn (brands such as Del Monte or Green Giant) is available at all supermarkets and is convenient for batch preparation. Full-fat milk and light cream are available in the dairy aisle (Meiji, Kowloon Dairy, and Anchor are reliable brands). Low-sodium stock cubes (e.g., Knorr) are widely available; for a lower-sodium option, make an unsalted vegetable stock from scratch.

Method

1. Heat a saucepan over a medium heat and add the butter or olive oil. Add the chopped onion and cook, stirring, until softened and translucent — approximately 5 minutes. Do not allow it to brown.
2. Add the corn kernels and stir for 2 minutes until slightly softened.
3. Pour in the stock. Bring to the boil, then reduce to a medium-low heat, cover and cook for 10 minutes until the corn is completely tender.
4. Allow to cool slightly (to approximately 65°C), then transfer the corn and all the stock to a blender. Blend on a high speed for 2–3 minutes until completely smooth.
5. Pass through a fine metal sieve to remove all corn skin and coarse fibre. This step is essential — corn skin remains even after thorough blending and poses a texture hazard.
6. Return the strained corn puree to the saucepan. Add the full-fat milk and light cream, and warm gently over a low heat. Do not bring to a rolling boil — cream and milk will separate.
7. If using milk powder or cream cheese, add at this stage and stir until fully dissolved or melted.
8. Season with a small pinch of salt and white pepper.
9. If the soup is too thin, mix the cornstarch with an equal amount of cold water to form a slurry, and stir gradually into the simmering soup until the desired Level 4 consistency is reached.

Texture Guidance

The finished cream of corn soup should be an even cream-yellow colour with a silky, uniform consistency — noticeably thicker than the Level 3 version. After straining, no corn skin or fibre should remain. Pressed with the back of a fork, the soup leaves a smooth, even coating; it does not flow rapidly when the bowl is tilted — meeting IDDSI Level 4 (minced and moist) consistency.

Cultural Background

Cream soup (忌廉湯, gei lim tong) is a staple of Hong Kong’s cha chaan teng (茶餐廳, Hong Kong-style café) menu, typically served alongside buttered toast as part of a set meal breakfast. Cream of corn is one of the most popular varieties, prized for its natural sweetness and gentle flavour. Adapting this familiar dish as a care food recipe allows elderly residents to enjoy a taste from everyday Hong Kong dining life, whilst ensuring it meets dysphagia safety standards.

Texture Tests

Fork pressure test: Passes Level 4 — the soup flows through the fork tines slowly, leaving a smooth, even cream-coloured coating on the back of the fork. No particles, corn skin, or fibres are visible.

Flow test: When the bowl is tilted, the soup flows slowly and evenly — not as rapidly as the Level 3 version — confirming it meets Level 4 consistency rather than Level 3.

Visual check: The colour is uniformly pale yellow. Any dark specks indicate corn skin fragments — the soup must be strained again if these are present.

Important Notes

• Corn skin is the primary texture hazard in this recipe: vigorous blending alone cannot remove it, and the fine sieve step must not be skipped.
• Do not bring to a rolling boil after adding the milk and cream — separation will affect both texture and appearance.
• Fresh corn is sweeter than canned but requires shucking and stripping the kernels. Canned corn is more convenient and consistent in quality for care kitchen batch cooking.
• For residents who are lactose intolerant, substitute the milk with unsweetened soy milk or oat milk — but confirm that the alternative meets Level 4 consistency after blending.

Serving Chilled in Summer

This soup is equally suitable at Level 4 when served chilled — a refreshing option in Hong Kong’s hot and humid summer months. When refrigerated, the soup thickens slightly; if it becomes too thick, add a small amount of cold milk to adjust. Ensure the soup is stored at safe refrigeration temperatures (below 4°C) at all times.

Storage and Reheating

Refrigerate in a sealed container for up to 2 days. When reheating, warm gently over a low heat with constant stirring to prevent scorching at the bottom. If the soup has thickened during refrigeration, add a small amount of milk or stock to restore the desired Level 4 consistency. Confirm the texture meets Level 4 after every reheating cycle.

Nutrition

Basic version approximately 220 kcal per serving; with added milk powder approximately 300 kcal. Corn provides natural sugars, dietary fibre, and B vitamins. Milk and cream contribute calcium and fat-soluble vitamins. For residents with poor appetite or who are underweight, increasing the cream content or adding milk powder is an effective way to boost caloric intake without increasing meal volume — a practical high-energy strategy for clinical nutrition support.
