Shoppers comparing snack portions
If you count calories per snack, distinguish a single plain cake from a flavoured jumbo cake or an entire portioned pack. Their declared figures describe different amounts of food.
Who is this for?
Shoppers ordering groceries for delivery
If a particular flavour, ingredient or nutrition figure matters, decide what substitutions you would accept before placing the order. Tesco allows substitution notes but says a requested alternative may not always be possible.
Shoppers checking salt or allergens
Look at the exact variant rather than the words ‘rice cakes’ alone. Salt declarations differ between the Kallo plain cakes and Snack a Jacks flavoured products, while Kallo Lightly Salted carries a precautionary warning for milk, sesame and soya.
What should you compare?
Start with the amount you expect to eat, then compare its nutrition and ingredients. Before checkout, decide whether another product would meet the same requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Check kcal per cake for individual cakes or per full pack for portioned snacks. The NHS notes that a manufacturer’s portion may differ from the amount you eat. | I want to compare the snack I would actually eat, not mistake a per-cake figure for a whole-pack figure. |
| Salt and flavour | Compare salt using the same portion basis. Kallo lists trace salt per Organic Unsalted cake; Snack a Jacks lists 0.26 g per Salt & Vinegar jumbo cake and 0.63 g per 23 g Salt & Vinegar singles pack. | A savoury flavour appeals to me, but I also want to see how much salt is in the cake or pack I choose. |
| Toppings | Check the rice cake and any spread or topping separately. The cake’s label does not describe the finished snack. | If I plan to add a topping, I need its calories and ingredients in the comparison too. |
| Ingredients and allergens | Read the ingredient list and precautionary allergen statement for the exact variant. Kallo Lightly Salted says it may contain milk, sesame and soya. | A ‘gluten free’ or ‘vegan-friendly’ description does not replace checking the allergen advice that matters to me. |
| Substitutions | Set any available substitution preference and check the delivered label. Tesco says shoppers can leave notes, although the requested substitute may not be available. | I would rather specify which flavours or ingredients are acceptable than assume a replacement has the same nutrition information. |
What is easy to overlook?
-
Comparing one cake with one whole pack
Kallo lists 27 kcal per plain cake, while Snack a Jacks lists 93 kcal for a 23 g Salt & Vinegar singles pack. Those figures cover different portions.
Compare calories for the number of cakes or packs you intend to eat.
-
Assuming a light snack has little salt
Kallo’s plain cakes list trace salt per cake, whereas Snack a Jacks lists 0.26 g per Salt & Vinegar jumbo cake. Flavour and format can change the comparison.
Read salt alongside calories, using the same portion basis for each product.
-
Counting the cake but not the topping
A rice cake’s nutrition declaration covers the cake, not a spread added afterwards.
Include the intended topping when comparing the calories, ingredients and allergens of the finished snack.
-
Accepting a different variant as a substitute
A replacement with another flavour or coating may have different ingredients and nutrition information. Tesco says substitution notes cannot always be accommodated.
State important preferences in your Tesco order and check the delivered product. Tesco says an unwanted substitute can be returned to the driver for a refund.
Brand and retailer references
These examples show why the exact product and serving basis matter; a brand name alone does not establish a nutrition profile.
Kallo
Its Organic Unsalted and Lightly Salted wholegrain rice cakes offer plain options with per-cake declarations.
- Kallo lists 27 kcal per cake for both products and trace salt per cake.
- Kallo Lightly Salted carries a precautionary ‘may contain’ warning for milk, sesame and soya.
Snack a Jacks
Its jumbo cakes and 23 g singles packs suit different ways of portioning a flavoured snack.
- The brand lists 41 kcal per Salt & Vinegar jumbo cake and 93–96 kcal per pack across the stated singles flavours.
- Salt varies by flavour and format: the listed Salt & Vinegar singles pack contains 0.63 g, compared with 0.21 g for Sweet Chilli.
Tesco
Tesco’s rice-cake category lists own-label products alongside Kallo and Snack a Jacks, including plain and coated formats.
- Tesco allows shoppers to leave substitution preferences for an online grocery order.
- Tesco says a requested substitute may not always be possible, so check what is delivered.
M&S
Its Lightly Salted Rice Cakes provide an own-label wholegrain brown-rice example.
- M&S declares 386 kcal, 0.33 g salt and 3.4 g fibre per 100 g for this product.
- To compare a cake-sized portion with another product, check the pack’s serving or weight information rather than treating per-100 g figures as per-cake figures.
Sainsbury's
Its listing for Kallo Blueberry & Vanilla Rice & Corn Cakes gives an example of a flavoured variant.
- The listing states 35 kcal per rice-and-corn cake and an average of 14 cakes per pack.
- Compare this flavoured rice-and-corn product on its own label rather than assuming it has the same ingredients as Kallo’s plain rice cakes.

Questions about rice cakes
Are all rice cakes alike in calories?
No. Kallo lists 27 kcal per cake for its Organic Unsalted and Lightly Salted products; Snack a Jacks lists 41 kcal per Salt & Vinegar jumbo cake and 93–96 kcal per 23 g singles pack, depending on flavour. Compare the amount you intend to eat: as the NHS notes, a declared portion may differ from yours.
Which of the plain Kallo options has less salt?
Kallo lists trace salt per cake for both Organic Unsalted and Lightly Salted, so those per-cake declarations do not establish a numerical difference. If avoiding added salt matters to your choice, distinguish the Unsalted variant from the Lightly Salted one and check the exact pack.
Should I count toppings when comparing calories?
Yes. A rice cake’s declared calories cover the cake, not anything spread on it. Check the topping’s portion and label separately to assess the finished snack.
What if Tesco substitutes a different rice cake?
Use Tesco’s substitution notes to describe acceptable alternatives, but check the delivered item because Tesco says preferences cannot always be accommodated. Tesco says you can return an unwanted substitute to the driver for a refund.
Does a gluten-free or vegan-friendly label settle an allergen question?
No. Read the exact product’s ingredient and precautionary allergen statements. For example, Kallo’s Lightly Salted rice cakes carry a ‘may contain’ warning for milk, sesame and soya.
