For repeated lunchboxes, start by looking for small, clearly sized units and check that the particular pack contains the dark chocolate you want. Full-size bar bundles and filled selections make more sense when sharing at afternoon tea is the main use; whichever format you choose, check the exact pack’s ingredients, allergens, nutrition label and storage instructions.
Look at the size of each unit, not just the number of items in the pack. Small bars may be easier to pack repeatedly than opening and dividing a full-size bar, while a larger bundle can still be used for sharing at home.
Check the cocoa percentage on each bar or selection. Ranges cited by Green & Black’s and Hotel Chocolat include different cocoa strengths, so the word “dark” alone does not identify the flavour of a particular product.
Read the ingredients, allergen information and suitability statements on the exact pack, especially for filled assortments. A dark-chocolate description does not establish that a product is suitable for someone with a milk or nut allergy.
Choose the unit format for the occasion first, then compare the labels of the specific products you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Portion format | Compare the number of units and grams per unit. Check whether the bars are small enough to use as packed or whether a larger bar would need dividing. | I want a repeatable lunchbox portion without opening a full-size bar each time. Montezuma’s lists a 10 × 25g Mini Chocolate Bar Library, while Lindt lists a 5 × 100g build-your-own selection; check the contents of the particular pack before relying on either for dark-chocolate portions. |
| Ingredients and allergens | Read the current ingredients, allergen declarations and suitability statements for the exact flavour or box. Check filled chocolates separately from plain bars. | If I am packing for someone with an allergy or serving guests, I need to know what is in the product I will actually share. GOV.UK’s UK allergen guidance says food businesses must provide allergen information for prepacked food. |
| Cocoa and sugars | Check the stated cocoa percentage and compare sugars per 100g on nutrition labels; consider the amount likely to be eaten. Do not use cocoa percentage as a substitute for the nutrition panel. | I may want a particular cocoa strength, but I still need the label to compare sugars. The NHS notes that chocolate can contain free sugars and that a label’s total-sugars figure can also include sugars that are not free sugars. |
| Sharing and storage | Check whether the pack contains plain bars or filled pieces, then follow its storage and best-before instructions. | For afternoon tea, I might prefer an assortment to put out for sharing. If some is being kept for later lunchboxes, I need to retain the packaging information for those portions. |
Filled selections can have different ingredients from plain bars. The chocolate type alone cannot establish suitability for someone with an allergy.
Read the current ingredients, allergen declaration and suitability statement on the exact pack before packing or serving it.
A multipack of full-size bars serves a different packing need from a pack of small units, even if both contain several items.
Compare the unit count and weight. Choose a format you can use as packed, or plan how a larger bar will be divided and stored.
Cocoa percentage describes part of a product’s composition; it does not state how much sugar is in the portion being eaten.
Compare the nutrition panels on the same basis, such as per 100g, and consider the portion you intend to serve.
Different centres can bring different ingredients and make a sharing box less straightforward to use for several lunchboxes.
Check each selection against the intended recipients and any school or household requirements. For tea-time sharing, keep the product information available to guests.

The 348g filled-chocolate box is a sharing format for afternoon tea rather than a plain-bar multipack. Check individual piece sizes and whether pieces are wrapped before using it for repeated lunchboxes, and read the current pack for allergens. The product information warns that it is not suitable for children under four because of a choking hazard.
No. Check the exact product’s current ingredients, allergen information and suitability statement; a filled selection can differ from a plain dark bar. GOV.UK’s UK allergen guidance says food businesses must provide allergen information for prepacked food.
Start by comparing the size of each unit. Montezuma’s lists a Mini Chocolate Bar Library of 10 × 25g bars, whereas Lindt’s build-your-own selection is listed as 5 × 100g; check the exact contents before assuming a pack offers small, all-dark portions.
No. Compare the nutrition information for the specific products, using the same basis and considering the portion served. The NHS explains that chocolate can contain free sugars and that the total-sugars figure on a label can also include sugars that are not free sugars.
Follow the storage and best-before instructions on its pack. If you divide the contents for later use, retain the packaging information so the ingredients and allergens can still be checked.
Read the ingredients and allergen information for the exact pack, including any suitability warnings. GOV.UK’s UK allergen guidance, dated 17 July 2026, says food businesses must provide allergen information for prepacked food; it does not mean every dark-chocolate product contains the same allergens.
