For a BBQ, choose hot chocolate by how you can prepare it rather than treating four pints as a required bottle size: the Tesco, Sainsbury’s and M&S listings discussed here describe powders and flakes sold by weight. A mix made with hot water suits a setup without milk-heating facilities; drinking chocolate or flakes suit one where you can heat milk. Check the exact pack recipe before planning servings, and its current allergen label before serving guests.
The useful starting point for a BBQ is what you can heat at the venue and what your guests can drink.
If you can prepare hot milk after grilling, drinking chocolate and chocolate flakes are both worth considering. Tesco’s instructions for Cadbury drinking chocolate and M&S’s instructions for its Belgian Milk Hot Chocolate Flakes use hot milk; check each pack for the amount needed per drink.
A product with water-based instructions is easier to plan around when you have a kettle or urn. Sainsbury’s lists Galaxy Instant Hot Chocolate as a water-mix product, with a serving basis of 25 g powder and 200 ml hot water.
Preparation method does not establish ingredient suitability. The reviewed Galaxy instant product lists milk-derived ingredients and soya lecithin, while the M&S flakes contain milk and soya and carry a nut-allergy warning. Check the current label of the exact product you intend to serve.
Decide which liquid you can heat first, then use the chosen pack’s instructions to plan quantities and check suitability for guests.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation liquid | Read whether the exact product calls for hot water or hot milk. Tesco’s Cadbury drinking-chocolate instructions use hot milk; Sainsbury’s Galaxy instant instructions use hot water. | If I can provide hot water but cannot heat milk at the BBQ, I need a product whose own instructions use water. |
| Guest suitability | Check ingredients and allergen warnings on the current pack, including for milk, soya and nuts where relevant. Do not infer that a water-mix drink is dairy-free. | When guests have allergies or dietary restrictions, I need to check the exact variant before I make or serve their drinks. |
| Servings and liquid | Use the pack’s powder amount and liquid volume per serving where stated. Sainsbury’s gives 25 g powder plus 200 ml water for a serving of Galaxy Instant Hot Chocolate; Tesco’s cited Cadbury instructions give three teaspoons but do not specify a milk volume. | I want enough drinks for the guest count without assuming that four pints of liquid will make the same number of servings with every mix. |
| Drink style | Compare the preparation method as well as the format. M&S describes its Belgian Milk Hot Chocolate Flakes as melting into hot milk and states 45% cocoa solids; Galaxy Instant Hot Chocolate has a stated hot-water method. | For drinks after grilling, I may prefer a milk-based flake or drinking-chocolate preparation if I can heat milk; otherwise, a water-mix option fits the equipment I have. |
The Tesco, Sainsbury’s and M&S examples discussed here are powders or flakes sold by weight. Four pints of milk or water describes liquid you might have available, not the pack size of those products.
Choose a preparation method first, then compare pack instructions with the liquid and equipment available at the BBQ.
Sainsbury’s lists Galaxy Instant Hot Chocolate as a drink made with hot water, but the product information also includes milk-derived ingredients and soya lecithin.
Read the ingredients and allergen declaration for the exact jar or sachet before serving anyone who needs to avoid milk or soya.
Recipes differ: Sainsbury’s states 25 g powder with 200 ml water for a Galaxy serving, whereas Tesco’s cited Cadbury instructions specify three teaspoons with hot milk without giving a milk volume.
Work from the chosen pack’s recipe and the number of guests. Check both the powder and liquid quantities rather than treating four pints as a fixed serving count.
An online description may not reflect the pack you are about to serve. That matters when products and variants have different ingredients or warnings.
Check the physical pack at purchase and keep its label available while serving, so guests can see the information for the drink being prepared.
These examples illustrate preparation formats and label checks; a brand name alone does not establish how every variant is made or what it contains.

Sainsbury’s lists a 370 g Galaxy Instant Hot Chocolate jar with a hot-water preparation method.
Tesco and Sainsbury’s category listings show Options jars and sachets, including different flavours and variants.
M&S describes its 250 g Belgian Milk Hot Chocolate Flakes as a product made with hot milk.

This is another drinking-chocolate option for a setting where you can prepare hot milk. Follow the current pack’s mixing instructions to calculate powder and milk for the guest count, and check its ingredient label before serving.
Use four pints as the amount of preparation liquid you might have, rather than assuming it is a hot-chocolate pack size. The Tesco, Sainsbury’s and M&S examples discussed here are powders or flakes sold by weight. Choose a product by its preparation method, then check its pack recipe to see how much liquid each drink needs.
A water-mix product is a practical choice if you can provide hot water but cannot heat milk. Sainsbury’s gives a 25 g powder and 200 ml hot-water serving basis for Galaxy Instant Hot Chocolate. Tesco’s cited Cadbury drinking chocolate and the reviewed M&S flakes instead use hot milk, so those choices need milk-heating facilities.
Do not assume so: the reviewed Galaxy instant product is mixed with water but lists milk-derived ingredients, and the Joybuy-listed Cadbury Highlights drink also contains milk ingredients. Check the current ingredient and allergen label of the exact product before serving it to a guest with a dietary restriction or allergy.
