For a coconut-based Sunday-roast sauce or gravy, start with canned cooking coconut milk: the Blue Dragon 400ml product listed by Sainsbury’s is described for sauces and soups, while Tesco lists 1L coconut drinks as a separate product type. Four UK pints are about 2.27L, so six 400ml cans provide 2.4L; check how much the recipe actually needs before buying that quantity, and follow each pack’s instructions for opened leftovers.
If coconut milk is an ingredient in gravy or another savoury accompaniment, look at canned cooking products and their stated uses rather than assuming a coconut drink will give the same result. Check the exact pack for ingredients and allergens.
A four-UK-pint requirement needs a pack-size calculation. The UK Product Regulation and Metrology Act 2025 defines a pint as 0.56826125L: four pints are 2.273045L, and six 400ml cans provide 2.4L. Buy for the recipe quantity, not simply the nearest round number of packs.
If the coconut product is for drinking or pouring over cereal, a 1L coconut drink may match the intended use. Tesco lists coconut drinks separately from canned coconut milk, and Alpro describes its plant-based range as coconut drinks rather than coconut milk.
Settle the recipe’s intended use first, then calculate the volume and check the exact product labels before choosing packs.
| Priority | What to check | Your needs |
|---|---|---|
| Cooking format | Check whether the recipe calls for cooking coconut milk or a coconut drink. Read the exact pack’s ingredients and stated uses; Sainsbury’s describes Blue Dragon’s 400ml coconut milk for sauces and soups. | I’m making a coconut-based gravy or sauce, rather than buying a drink to serve alongside the meal. |
| Pack quantity | Under the UK Product Regulation and Metrology Act 2025, four UK pints equal 2.273045L. Six 400ml cans supply 2.4L; check the volume of any pack labelled by weight before counting it towards a liquid-volume requirement. | The recipe calls for roughly four pints, but I only want to open as much cooking coconut milk as the batch needs. |
| Allergens | Read the current ingredients and precautionary statements. Sainsbury’s Blue Dragon 400ml listing says it may contain peanuts and nuts; GOV.UK explains that regulated allergens used as ingredients must be identified on prepacked food labels. | I’m cooking for guests and need to check the specific product against their allergy requirements, not rely on a plant-based description. |
| Opened storage | Follow each pack’s transfer, refrigeration and use instructions. Sainsbury’s listings say to use opened KTC and Blue Dragon 400ml coconut milk within two days, and its Aroy-D 400ml listing within three days. | Will there be opened coconut milk left after the gravy is made? I need a plan for using it within the pack’s stated period. |
| Nutrition label | Compare figures on the same stated basis and for the exact variant. Sainsbury’s Aroy-D 400ml listing gives 17g saturates per 100ml; a figure stated per 100g is a different comparison basis. | If the recipe uses several cans, I want to read the nutrition panels as well as choose the flavour and quantity the dish calls for. |
Tesco lists 1L coconut drinks separately from culinary coconut milk, while the checked Blue Dragon can is described for sauces and soups. A drink carton’s category does not establish how it will behave in a gravy.
Check what the recipe specifies. For a coconut-based sauce, compare the intended cooking uses and ingredients on the exact canned products; choose a drink when the recipe calls for one.
Four UK pints are about 2.27L, according to the pint definition in the UK Product Regulation and Metrology Act 2025. Six 400ml cans give 2.4L, which may be more than a small batch of gravy requires.
Measure the amount needed for the whole recipe before choosing how many cans to buy or open. Follow the pack’s storage instructions for any opened remainder.
The Blue Dragon 400ml coconut milk listed by Sainsbury’s says it may contain peanuts and nuts. A plant-based description does not replace the product’s ingredient and precautionary statements.
Check the current pack against the requirements of anyone eating the meal, including statements about possible cross-contact.
The checked Sainsbury’s Aroy-D listing states saturates per 100ml, while other product information may state values per 100g. Those figures should not be treated as a like-for-like ranking.
Read the nutrition panel for the exact product and compare values only when their stated quantities and units match.
These examples describe particular listed products or drink ranges, not every product made by each brand.

These canned cooking coconut milk options are relevant when the roast recipe calls for a coconut-based sauce or other savoury dish. For a four-pint quantity, calculate from each pack’s liquid volume; a pack labelled by weight needs its volume checked separately.

This cooking coconut milk is labelled 400G, a weight rather than a liquid volume. Check its stated volume before calculating a four-pint quantity, and read the current pack’s nutrition, allergen and opened-storage information.
Six cans provide 2.4L, slightly more than four UK pints. The UK Product Regulation and Metrology Act 2025 defines a pint as 0.56826125L, making four pints 2.273045L. Check whether your recipe actually calls for that much cooking coconut milk before buying six cans.
Use a coconut drink when the recipe calls for one; do not assume it will give the same result as a cooking milk. Tesco lists 1L coconut drinks as a separate product type, while Sainsbury’s describes its Blue Dragon 400ml cooking coconut milk for sauces and soups.
Follow the instructions on the exact pack. Sainsbury’s listings say to refrigerate opened KTC and Blue Dragon 400ml coconut milk and consume it within two days; its Aroy-D 400ml listing says to refrigerate and use it within three days. Transfer the contents to another container where the label instructs you to.
Do not determine allergy suitability from “plant-based” wording alone. Sainsbury’s Blue Dragon 400ml listing says it may contain peanuts and nuts. Check the current product’s ingredients and precautionary statements against the individual’s requirements.
Coconut milk alone does not determine whether the finished gravy is dairy-free: check the stock, fat, thickener, seasonings and other ingredients too. Tesco Real Food’s dairy-free roast gravy recipe, for example, specifies dairy-free vegetable stock alongside tamari and cornflour.
