For a low labelled calorie count per cake, start with plain or lightly salted rice cakes: Tesco lists 26 kcal per cake, Kallo 27 kcal and ASDA 30 kcal for the named products. Check the eating unit before comparing flavoured options, then check ingredients and allergen warnings on the pack. If you need a particular product for your journey, buy it before travelling rather than relying on airport shop stock.
If you want a dry snack to pack for the journey, compare the amount you expect to eat. Tesco Groceries lists its Lightly Salted Rice Cakes at 26 kcal per cake, Kallo lists its Lightly Salted cakes at 27 kcal per cake, and ASDA Groceries lists its Slightly Salted cakes at 30 kcal per cake.
Kallo describes its Lightly Salted Rice Cakes as gluten free and suitable for vegans, but also says they may contain milk, sesame seeds and soya. If you need to avoid an allergen, read the warning on the pack you are buying.
Heathrow Airport lists WHSmith shops across its terminals and says they sell food and drink. That does not establish whether a particular rice cake, flavour or pack size will be on the shelf when you travel.
Choose the amount you would eat during the journey first; then compare labels using the same portion basis and check any requirements that could rule out a pack.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Check whether energy is stated per cake or per serving. Tesco Groceries lists 26 kcal per cake for Tesco Lightly Salted; Kallo lists 27 kcal per cake for Kallo Lightly Salted; ASDA Groceries lists 30 kcal per cake for ASDA Slightly Salted. Tesco Groceries lists Snack a Jacks Caramel Jumbo at 50 kcal per 13 g serving, a different portion basis. | I want to compare the amount I am likely to eat, not just pick the smallest number on two differently labelled packs. |
| Flavour and ingredients | Check the flavour, ingredients and sugars per labelled serving. Tesco Groceries lists 2.4 g sugars per 13 g serving for Snack a Jacks Caramel Jumbo; plain and lightly salted products have different ingredients and serving declarations. | A sweet or savoury flavour matters to me, but I still want to know what one labelled serving contains. |
| Dietary and allergen labels | Read the current pack’s suitability statements and may-contain warnings. Kallo says its Lightly Salted cakes are gluten free and vegan-friendly but may contain milk, sesame seeds and soya; Tesco Groceries also lists may-contain warnings for its Lightly Salted cakes. | If I need to avoid a particular ingredient or allergen, a broad dietary label alone is not enough to make my choice. |
| Airport plans | Decide whether to pack a dry snack or check the relevant terminal shop. GOV.UK says food in hand luggage can lead to an additional security check; Heathrow Airport’s listing of food retailers does not confirm stock of a named rice cake. | I would rather bring a pack whose label I have checked than depend on finding the same product after security. |
Tesco Groceries, Kallo and ASDA give the named lightly salted products’ energy per cake, while Tesco Groceries gives Snack a Jacks Caramel Jumbo’s energy per 13 g serving. Those figures are not automatically like-for-like measures of the amount you will eat.
Check the labelled unit and consider how many cakes or servings you plan to take.
Kallo labels its Lightly Salted cakes gluten free and vegan-friendly, yet warns that they may contain milk, sesame seeds and soya. Tesco Groceries also lists may-contain warnings for its Lightly Salted cakes.
Check the current pack’s ingredients and allergen statements for the specific product you choose.
Heathrow Airport says its WHSmith shops sell food and drink, but that does not confirm the stock of any particular rice cake.
When the labelled portion, ingredients or flavour matter to your choice, buy the pack before travelling or check the relevant terminal retailer.
GOV.UK treats liquid and semi-liquid foods, including jam and honey, as liquids. It says that at most UK airports, liquids in containers larger than 100 ml cannot pass through security; requirements can differ by airport.
Check the departure and any transfer airport’s rules for a topping you plan to carry, or buy it after security.

Kallo’s Lightly Salted Rice Cakes are a plain option for comparing calories per cake and checking dietary suitability.
Caramel Jumbo offers a sweet rice-cake option with a labelled 13 g serving rather than the per-cake basis used for the named plain options.
Tesco Lightly Salted Rice Cakes provide a per-cake figure for shoppers comparing the named plain options.
ASDA Slightly Salted Rice Cakes are another plainly flavoured option to compare before travelling.
M&S lists lightly salted, chocolate and high-protein rice-cake varieties for shoppers choosing between different product types.
These Joybuy options include a lightly salted organic rice cake and flavoured rice or rice-and-corn cakes to consider for a journey. The Kallo Organic product here is a different variant from the non-organic Kallo Lightly Salted product whose 27 kcal figure is discussed above; check each selected pack’s own nutrition and allergen label.

A lightly salted option if you prefer a plain-flavoured cake for the journey. This is the organic 130g variant; use its own pack to check calories per cake and allergen warnings.
No image available
An apple-and-cinnamon option if you want a flavoured cake rather than a lightly salted one. Check the 127g pack for its labelled serving, sugars and allergen statement.
No image available
A blueberry-and-vanilla rice-and-corn option for a flavoured travel snack. Check the 131g pack’s portion basis, sugars and allergen information when comparing it with plain cakes.
No image available
A sour-cream-and-chive option if you prefer a savoury flavour. Check the 117g pack’s serving and allergen information, particularly if you need to avoid milk.
GOV.UK’s hand-luggage guidance does not identify dry rice cakes as a prohibited item, but says food can obstruct X-ray images and lead to an additional manual bag check. Check your airline’s hand-luggage allowance and follow security staff’s instructions.
Check the spread against the airports’ liquid rules rather than treating it like a dry rice cake. GOV.UK includes liquid and semi-liquid foods such as jam and honey in those rules and says containers larger than 100 ml cannot pass through security at most UK airports; check departure and transfer airports separately.
Do not rely on a particular pack being available. Heathrow Airport lists WHSmith shops selling food and drink across its terminals, but that does not confirm stock of a specific rice-cake brand or flavour. Bring the product you have chosen or check the relevant terminal retailer.
No: check each allergen separately on the current pack. Kallo describes its Lightly Salted Rice Cakes as gluten free, but says they may contain milk, sesame seeds and soya.
