For cooking in a student flat, stocking individual 400ml tins makes sense if your meals will use each opened tin within its storage instructions. Powder lets you prepare an amount to match a recipe, but the Maggi example contains milk; a 1L coconut drink is a separate choice for cereal or beverages, not a like-for-like cooking substitute.
If you expect to cook curries, soups or desserts, think about cupboard space, shared-fridge space and when you will use an opened tin. Shopping location may matter too: in SOS-UK’s September 2018 survey of approximately 1,500 students, 75% said location or convenience influenced where they shopped for food.
If a recipe uses less than a tin, powder or a plan for the remainder may be more useful than buying more unopened units. In WRAP’s 2025 survey of UK adults responsible for household food shopping or preparation, 62% reported choosing smaller packs to suit household size.
For cereal, smoothies or hot drinks, compare products labelled as coconut drinks separately from cooking coconut milk. Koko and Alpro describe the researched 1L products as drinks.
Choose when: Your planned curries, soups or desserts will use a tin or its remainder within the pack’s opened-life instructions.
Allow for: Unopened tins can be kept as directed on the pack, but an opened tin needs prompt use and refrigerated storage where instructed.
Choose when: You cook with coconut milk occasionally and want to prepare the amount specified by the powder’s directions.
Check first: Sainsbury’s lists sodium caseinate (milk) in Maggi Coconut Milk Powder Mix, so that product is not dairy-free.
Choose when: You want coconut drink for cereal, smoothies or beverages.
Keep in mind: A coconut drink is not a like-for-like replacement when a recipe calls for cooking coconut milk.
Match pack size to planned meals before filling a cupboard. WRAP’s Household Food Management Survey 2025 interviewed 5,509 UK adults responsible for food shopping or preparation online between 30 June and 14 July 2025; its pack-size responses can overlap.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Count the 400ml tins your planned recipes will use. Check whether each product is a single unit or a bundle, and where unopened units should be stored. | I want enough for the meals I have planned, without opening more than I can use. WRAP reports that 80% of surveyed adults bought larger packs for perceived value, while 62% chose smaller packs to suit household size; these behaviours are not mutually exclusive. |
| Opened storage | Read the exact pack’s refrigeration and use-by instructions after opening. Sainsbury’s lists a three-day opened life for its Aroy-D and Tropical Sun 400ml cooking milks. | If I only need part of a tin, I need a meal plan for the rest within that product’s stated period. |
| Intended use | Check whether the label describes cooking milk or a drink. Sainsbury’s lists 70% coconut extract for Aroy-D cooking milk and 9% coconut milk for Koko Unsweetened Coconut UHT drink; these are different ingredient measures and products. | I want cooking coconut milk for a recipe that calls for it, rather than assuming a drink will give the same result. |
| Ingredients | Read the ingredient and allergen information on the exact pack. Sainsbury’s lists sodium caseinate (milk) in Maggi Coconut Milk Powder Mix. | When sharing food in a flat, I need to check whether the particular product suits the people eating it. |
| Recipe format | For powder, follow the product’s preparation quantities. For a reduced-fat cooking milk, compare the exact product and what the recipe calls for rather than assuming it is interchangeable with another format. | If I cook only occasionally, I would rather choose a format that fits the recipe than keep an opened pack without a plan to use it. |
Sainsbury’s lists Koko Unsweetened Coconut UHT as a drink containing 9% coconut milk, while its Aroy-D cooking milk lists 70% coconut extract. They are distinct formulations, not interchangeable versions of the same product.
For a curry, soup or dessert, check that the product is sold as cooking coconut milk. Choose a drink when that is what you intend to pour over cereal or add to a beverage.
Unopened stock may fit in a cupboard, but opening a tin starts its product-specific storage period. Sainsbury’s instructs customers to refrigerate its Aroy-D and Tropical Sun cooking milks after opening and use them within three days.
Count the tins against planned recipes, then follow each pack’s instructions for any remainder.
Sainsbury’s lists sodium caseinate (milk) in Maggi Coconut Milk Powder Mix. A coconut product name alone does not establish whether it contains milk ingredients.
Read the current ingredient list and allergen information on the exact pack before serving it to a housemate.
Sainsbury’s Tropical Sun product information describes separation into thicker cream and thinner liquid as normal for that product.
Follow the pack’s shaking or stirring directions where given, while still observing its storage instructions and date marking.

Not as a like-for-like substitute. Sainsbury’s lists Koko Unsweetened Coconut UHT as a drink containing 9% coconut milk, while its Aroy-D cooking milk lists 70% coconut extract. Check which format the recipe calls for; choose a coconut drink for cereal or beverages.
Follow the exact product’s instructions. Sainsbury’s says its Aroy-D and Tropical Sun 400ml cooking coconut milks should be refrigerated after opening and consumed within three days; do not apply a coconut drink’s instructions to a tin.
