Hosts serving guests with different tastes
If you do not know how much bitterness everyone enjoys, a plain 70% bar is a starting point. Divine describes its 70% bar as having subtle sweetness; its 85% bar has a more pronounced bittersweet profile.
Who is the bar for?
Guests who seek intense cocoa flavours
An 85% bar is worth considering when the intended guests already like distinctly bittersweet chocolate. Montezuma’s 100% cocoa Absolute Black is a more specialised, no-added-sugar option.
Hosts managing guests’ allergies
Choose by the exact pack’s ingredients and precautionary warnings, not by cocoa percentage or a vegan description. Keep that information available when the bar is shared.
What should you check?
Decide whose tastes the single bar needs to suit, then check the exact product label before putting it on the buffet.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa profile | Compare the stated cocoa percentage and the maker’s flavour description. Divine describes its 70% bar as subtly sweet and its 85% bar as bittersweet; Montezuma’s Absolute Black contains 100% cocoa. | I need one bar for guests with different tastes, so I would start with plain 70%. If they actively prefer intense cocoa, I can choose 85% or 100% instead. |
| Added flavours | Check whether the exact bar is plain or contains flavour additions or a filling. Read its own ingredients and allergen information rather than relying on a description of the wider range. | A plain bar leaves fewer flavour preferences to guess. I would choose an added flavour only if I knew the guests wanted it. |
| Allergens | Read the current pack for ingredients and ‘may contain’ statements. The Lindt Excellence 70% bar, for example, says it may contain nuts, milk, soya and sesame seeds. | If a guest has an allergy, I need the information for the exact bar on the table. I cannot treat ‘vegan’ or ‘dark’ as an allergy-safety statement. |
| Serving format | Check the bar weight, the best-before date and the pack’s storage instructions. Decide how you will leave the wrapper accessible when serving pieces. | I want a single bar that fits the number of people sharing it, with its label available for anyone who needs to check it. |
What could go wrong?
-
Assuming every dark bar tastes much the same
A 100% cocoa bar may be an unwelcome choice if guests expect a sweeter buffet chocolate; the stated flavour profiles of the 70%, 85% and 100% examples differ.
For unknown preferences, begin with a plain 70% bar. Choose a more intense bar when you know the people sharing it enjoy that style.
-
Reading ‘vegan’ as milk-allergy clearance
A recipe description does not rule out a precautionary milk warning. The verified dark-bar examples carry different allergen statements.
Check the current pack’s ingredients and ‘may contain’ wording against each guest’s disclosed allergies; do not promise suitability from the words ‘vegan’ or ‘dark chocolate’.
-
Choosing a flavour without checking the variation
Dark-chocolate ranges include plain bars as well as bars with additions. A flavour or filling changes what guests will be served and may change the allergen information.
For one shared bar, choose a flavour only when it is wanted. Keep its own wrapper available and consider cross-contact with other buffet foods.
-
Relying on an earlier listing for the event
Product details and availability can change before Boxing Day, so an earlier listing cannot confirm the bar you will receive.
Check the exact bar when buying it, including its best-before date, and read the physical pack again before serving.
Relevant brand references
These examples help distinguish bar styles; a brand’s wider range does not establish the ingredients or allergens of an individual bar.

Questions about serving one bar
Which cocoa percentage should I choose for mixed guests?
A plain 70% bar is a starting point if you do not know guests’ preferences. Divine describes its 70% bar as subtly sweet and its 85% bar as more bittersweet; choose an 85% or 100% option when you know guests want a more intense cocoa profile.
Does vegan dark chocolate suit someone with a milk allergy?
Not necessarily. A vegan recipe does not rule out milk cross-contact: Lindt’s Excellence 70% bar, for example, carries a ‘may contain milk’ warning. Check the exact pack against the guest’s allergy rather than relying on the recipe description.
How can guests check allergens at a home buffet?
Keep the exact bar’s wrapper available when serving it, so guests can read its ingredients and precautionary statements. If you transfer pieces to a plate, make clear which wrapper belongs to them and consider cross-contact with other foods.
Is an online ingredients list enough before serving?
Use it to shortlist a bar, then read the physical pack before serving. M&S advises customers to check product labels because recipes and allergen information can change.
How should I store the bar before Boxing Day?
Follow the instructions on the bar you buy. The M&S 100g dark bar’s stated instructions are to store it in a cool, dry place away from sunlight; check your chosen pack rather than assuming every bar has identical directions.
