Choose an instant hot chocolate labelled for hot water if you do not want to open milk after Christmas dinner; Tesco Groceries lists Galaxy Instant Hot Chocolate 370 g with hot-water instructions, although it contains milk and soya. If you have milk ready to serve, Cadbury and M&S drinking chocolates specify hot milk; a dark option such as M&S 72% Dark is a separate flavour choice, not a way around milk or soya allergy checks. Plan the milk’s storage separately from the dry powder and read the current pack before serving guests with allergies.
Who is each option for?
The first choice is whether you will have hot milk available when drinks are served; flavour and guest-specific allergen checks follow from that plan.
Hosts with limited fridge space
If you would rather not open another carton of milk after dinner, look for instructions that explicitly say to add hot water. Water preparation does not establish that the powder is dairy-free: Tesco Groceries lists milk and soya for Galaxy Instant Hot Chocolate 370 g.
Hosts serving hot-milk drinks
If filtered, fresh or long-life milk is part of your drinks plan, a drinking chocolate with hot-milk instructions fits that method. Check the milk carton’s date and directions for storage after opening separately from the powder’s instructions.
Hosts offering a darker chocolate choice
If guests have asked for a dark-chocolate flavour, M&S lists a drinking chocolate with 72% minimum cocoa solids. Its product information also says it is not suitable for people with a milk or soya allergy, so flavour is not a substitute for checking dietary suitability.
What should you check before choosing?
Settle the preparation liquid first, then check dates, storage and the exact pack’s allergen statement before deciding how much to buy for guests.

What to check |
Your needs |
| Preparation liquid |
Read the mixing directions, not just the word “instant”. Tesco Groceries specifies hot water for Galaxy Instant Hot Chocolate 370 g, but hot milk for Cadbury Drinking Chocolate 500 g. |
I want to make drinks with kettle water without opening milk, or I have hot milk ready for an after-dinner cup. |
| Milk planning |
Check the milk carton’s date and after-opening directions separately. GOV.UK advises refrigeration at 5°C or below when a food’s label requires it after opening. |
I’m buying powder ahead but need to know how I’ll store the filtered, fresh or long-life milk once opened. |
| Allergens |
Read the current ingredients and allergen statement on the exact pack. Tesco Groceries lists milk and soya for Galaxy’s water-made product and “MAY CONTAIN MILK” for Cadbury Drinking Chocolate. |
A guest has an allergy, so neither a water-based recipe nor a dark-chocolate name is enough to establish suitability. |
| Chocolate style |
Compare the stated flavour and preparation method. M&S lists 72% minimum cocoa solids for its dark drinking chocolate and says the product is not suitable for people with a milk or soya allergy. |
For guests who prefer a darker chocolate flavour, I can offer a separate choice if its preparation and allergen details fit the serving plan. |
What can go wrong with the serving plan?
-
Buying drinking chocolate when only kettle water is planned
Tesco Groceries gives hot-milk directions for Cadbury Drinking Chocolate, while its Galaxy Instant Hot Chocolate listing specifies hot water. The distinction matters when drinks need to be made after the meal without opening milk.
Decide which liquid you will serve, then follow the preparation directions on the exact pack you buy.
-
Using the powder’s date to plan the milk
Dry powder and milk have separate dates and storage instructions. GOV.UK distinguishes a best-before date, which concerns quality, from a use-by date, which concerns safety; after-opening directions also matter.
Check that the powder’s date covers dinner, then check the milk carton independently and follow its instructions once opened.
-
Assuming “dark” or “made with water” means dairy-free
Tesco Groceries lists milk and soya for Galaxy Instant Hot Chocolate and “MAY CONTAIN MILK” for Cadbury Drinking Chocolate. M&S says its 72% Dark Drinking Chocolate is not suitable for people with a milk or soya allergy.
For a guest with an allergy, check the current physical pack of the exact product rather than relying on its flavour or mixing method.
Which brand ranges illustrate the options?
These examples show how preparation instructions and allergen statements can differ between products, including products from the same retailer.
Cadbury
Tesco Groceries lists Cadbury Drinking Chocolate 500 g as a powder prepared with hot milk.
- The listed recipe uses three teaspoons with hot milk, giving hosts a preparation direction to plan around.
- Its listed allergen wording says “MAY CONTAIN MILK”; check the current pack for anyone with an allergy.
Galaxy
Tesco Groceries lists Galaxy Instant Hot Chocolate 370 g with hot-water preparation instructions.
- The listed portion is 25 g of powder with 200 ml of hot water, so this product does not require milk for mixing.
- The same listing declares milk and soya; making it with water does not make the product dairy-free.
Options
Tesco Groceries lists Options flavours including salted caramel and Belgian chocolate, with a Belgian chocolate sachet format.
- A sachet may be useful when serving a separate flavour to one guest.
- Check the chosen flavour’s pack for its mixing liquid, ingredients and allergens; range-wide assumptions are not enough.
Tesco
Tesco Groceries lists an own-label instant hot chocolate alongside other brands in its hot-chocolate category.
- The category listing offers a way to compare pack formats and flavours when planning several drinks.
- Use each individual product’s instructions and allergen statement; a category listing does not establish that products share a recipe.
M&S
M&S lists standard drinking chocolate, instant hot chocolate and a 72% Dark Drinking Chocolate as distinct products.
- Its standard drinking chocolate specifies hot milk, while the dark product states 72% minimum cocoa solids.
- M&S says its standard drinking chocolate is not suitable for people with a milk allergy; its 72% dark product is not suitable for people with a milk or soya allergy.

Questions about serving and storage
Can every hot chocolate powder be made with water?
No. Follow the exact product’s instructions: Tesco Groceries lists hot-water preparation for Galaxy Instant Hot Chocolate 370 g, but hot milk for Cadbury Drinking Chocolate 500 g. M&S also specifies hot milk for its standard Drinking Chocolate.
Does long-life or filtered milk still need a storage plan?
Yes. Follow the milk carton’s own date and after-opening instructions rather than applying the powder’s directions to the milk. GOV.UK says food labelled for refrigeration after opening should be kept at 5°C or below; it also distinguishes best-before dates, which concern quality, from use-by dates, which concern safety.
Can I buy the powder ahead of Christmas dinner?
Check that the exact pack’s best-before date covers the meal and follow its storage instructions. M&S lists cool, dry storage for its Drinking Chocolate and Instant Hot Chocolate and says to consume those products within four weeks of opening; check the directions for whichever powder you choose.
Is dark or water-made hot chocolate suitable for a guest with a milk allergy?
Do not assume so. Tesco Groceries lists milk in Galaxy Instant Hot Chocolate despite its hot-water recipe and says Cadbury Drinking Chocolate “MAY CONTAIN MILK”. M&S says its 72% Dark Drinking Chocolate is not suitable for people with a milk or soya allergy. Check the current physical pack of the exact product against the guest’s allergy requirements.
