Fortified Milk Oatmeal | IDDSI Level 3 Recipe

IDDSI Level 3 (Liquidised) | 15 minutes | Easy

Replacing water with whole or calcium-enriched milk when cooking oats significantly boosts the nutritional profile: each serving provides approximately 250mg calcium (from milk) and 10g protein — more than double the protein of water-based oatmeal (approx 4g). Particularly suited as a breakfast for elderly patients at risk of osteoporosis or with insufficient protein intake, or as a fortified afternoon supplement.

Ingredients (serves 1)

Main ingredients:

• Quick oats 50g
• Whole milk or calcium-enriched milk 300ml (do not substitute skimmed milk — fat aids fat-soluble vitamin absorption)

Nutritional boosters (optional — choose one):

• Milk powder 1 tbsp (additional calcium and protein)
• Unflavoured whey protein powder 15g (raises protein to ~20g per serving)

Seasoning:

• Honey ½ tsp (optional)
• Vanilla extract 2–3 drops (optional, for aroma)

Method

1. Heat milk (with milk powder or protein powder, if using) in a saucepan over medium heat to near-boiling (small bubbles appear at edges, not a full rolling boil).
2. Add oats; stir continuously to prevent sticking. Cook 5–7 minutes until oats are completely soft and dissolved.
3. Remove from heat; blend thoroughly with a stick blender until completely smooth (at least 60 seconds).
4. If too thick, add a little warm milk; confirm Level 3 flow by tilting a spoon.
5. Stir in honey if desired. Serve immediately in a bowl.

Texture Testing

Flow test: Passes Level 3 — oatmeal flows off a tilted spoon and spreads flat in the bowl, losing shape within 5 seconds.

Particle check: After thorough blending, no oat particles or fibres remain. Texture resembles a smooth cream soup.

Spoon test: Flows slightly slower than plain milk, similar to thick soup; does not hold shape on a tilted spoon.

Safety Notes

⚠️ Milk heating — Avoid a full rolling boil, which denatures milk protein and causes skin formation, altering texture. Heat to 65–70°C (near-boiling) before adding oats.

⚠️ Thickening on standing — Oat beta-glucan continues absorbing liquid as it cools, causing noticeable thickening. Recheck texture before serving and thin with warm milk if necessary.

⚠️ Lactose intolerance — Use lactose-free milk (e.g. Lactaid) or unsweetened soy milk to maintain comparable calcium and protein levels.

⚠️ Protein powder selection — If using whey protein powder, choose unflavoured with no artificial sweeteners or colours. Patients with renal impairment should consult a healthcare professional before adding protein powder.

Sourcing Outside Hong Kong

For international care kitchens and home cooks outside Hong Kong, Cantonese ingredients are widely available at East and Southeast Asian grocery stores:

• United Kingdom: Wing Yip (Birmingham, London, Manchester), See Woo (London), Loon Fung (London)
• United States: 99 Ranch Market (West Coast), H Mart (East Coast), local Chinatown grocers
• Canada: T&T Supermarket (national chain), local Asian markets
• Australia: Burlington Supermarket, Tang’s, local Chinese grocers in Chinatown precincts
• Singapore & Malaysia: Sheng Siong, NTUC FairPrice (Singapore); Tesco, Mydin (Malaysia)
• Online: Sous Chef (UK/EU), Amazon.com (US), Yami.com (US)

Rolled or quick oats: universally available at mainstream supermarkets (Quaker, Bob’s Red Mill).

If a specific ingredient is unavailable in your region, the recipe notes alternative substitutions in the Ingredients section. For dishes requiring fresh Cantonese-specific ingredients (e.g. preserved century egg, fresh rice noodle rolls), check with your local East Asian grocer before substituting — texture compliance for IDDSI levels may require specific products.

Nutrition Notes

Per serving (approx 350ml, without protein powder): ~290 kcal, protein 10g, calcium 250mg, fibre 3g, vitamin D (if fortified milk used) ~2μg. With whey protein powder, protein rises to approximately 25g per serving. This recipe provides approximately 25% of the daily calcium target of 1000–1200mg recommended for adults over 60 years.
