Picnic planners counting portions
A kcal-per-cake figure helps you account for the number you intend to pack and eat. Compare that figure on the exact product rather than treating every rice cake as the same portion.
Who is choosing rice cakes?
The useful comparison depends on whether the rice cake is the snack itself or the base for a larger lunch.
Shoppers adding toppings
A plain cake leaves room for savoury or sweet toppings, but the finished lunch also includes the topping’s ingredients and calories. Consider whether anything you add normally needs refrigeration.
Shoppers checking dietary labels
Vegetarian, vegan or gluten-free wording answers only part of the question. Read the exact pack’s ingredients and allergy advice, including any may-contain statement, before packing food for someone with an allergy.
What should you compare?
Start with the portion you will actually eat, then compare its nutrition and ingredients. Plan chilled toppings as part of the picnic, not as an afterthought.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portions | Read kcal per cake or stated serving and the serving weight; count how many you plan to eat. Kallo lists its Lightly Salted cake at 27 kcal, while Tesco lists its own Lightly Salted cake at 27 kcal per 7.2 g cake. | If I am making several topped cakes for lunch, I need to count both the cakes and everything I put on them. |
| Plain or flavoured | Decide whether you want a neutral topping base or a snack you can eat as packed. Tesco lists Snack a Jacks Sour Cream & Chive at 37 kcal per 9.7 g snack and Caramel at 50 kcal per 13 g snack. | A ready-flavoured cake would save me packing a separate topping; a plain one gives me a choice of toppings at the picnic. |
| Nutrition and ingredients | Compare per-100 g figures as well as per-cake figures when serving sizes differ. Tesco lists 0.02 g salt per cake for its Lightly Salted product and 2.4 g sugars per snack for Snack a Jacks Caramel. The NHS notes that manufacturers’ portions may differ. | I want to see what is in the particular flavour I am buying, not assume that a plain cake and a coated or flavoured cake have the same figures. |
| Allergens | Check ingredients and may-contain advice on the current pack. Kallo says its Lightly Salted product may contain milk, sesame seeds and soya; Tesco lists milk-containing ingredients in Snack a Jacks Sour Cream & Chive. | If someone at the picnic has an allergy, I need the label for the exact product, even when its dietary-suitability wording looks relevant. |
| Picnic storage | Pack foods you would normally refrigerate in a cool box or cool bag with ice or frozen gel packs, as the Food Standards Agency advises. Keep toppings separate until you are ready to assemble the cakes if you want to protect their texture. | For a lunch with chilled dips or spreads, I need a way to carry those foods cool; the dry rice cakes alone do not settle the storage plan. |
Picnic lunch mistakes to avoid
-
Treating every rice cake as the same portion
Calories vary by product and cake size. Tesco lists its Lightly Salted cake at 27 kcal, its Snack a Jacks Caramel snack at 50 kcal, and Kallo lists a milk-chocolate rice cake at 84 kcal.
Check kcal per cake or serving on the pack, then account for the number you intend to eat.
-
Counting the cake but not the topping
Spreads, dips and other additions change the finished lunch. A topping that is normally kept in the fridge also changes how the food must be carried.
Plan the topping and its quantity alongside the cakes. The Food Standards Agency advises carrying normally refrigerated foods in a cool box or cool bag with ice or frozen gel packs.
-
Relying on one dietary label
Kallo describes its Lightly Salted rice cakes as gluten free and suitable for vegans, yet also states that they may contain milk, sesame seeds and soya. Flavoured cakes can have different ingredients.
Read the current ingredient list and allergy advice for the exact pack, particularly when packing food for someone with an allergy.
-
Leaving chilled picnic food in the warmth
Dry rice cakes do not remove the storage requirements of chilled toppings and accompanying foods. The Food Standards Agency warns that time out of refrigeration matters, especially in very hot weather.
Keep normally refrigerated foods cool. In extremely hot weather, the Food Standards Agency advises using food that has been out of the fridge within 2 hours.
Brand and product-line references
These examples show why it helps to compare individual products rather than assigning one calorie or allergen profile to a whole brand.
Kallo
Kallo lists both plain wholegrain and chocolate-coated rice cakes; their per-cake figures should be considered separately.
- Kallo states 27 kcal per cake for its Lightly Salted product.
- Kallo lists 84 kcal per cake for its milk-chocolate product. Its Lightly Salted product carries a may-contain statement for milk, sesame seeds and soya.
Snack a Jacks
The flavoured jumbo cakes offer a snack that does not require a separate picnic topping.
- Tesco lists Sour Cream & Chive at 37 kcal per snack and Caramel at 50 kcal per snack.
- Check each flavour independently: Tesco lists milk-containing ingredients for Sour Cream & Chive and 2.4 g sugars per snack for Caramel.
Tesco
Tesco’s own-label Lightly Salted rice cakes provide a plain brown-rice option for a topped lunch.
- Tesco lists 27 kcal, 0.02 g salt and less than 0.1 g sugars per 7.2 g cake.
- Check the current pack when buying, especially if its ingredients or allergy advice affect your choice.
M&S
M&S describes its Lightly Salted cakes as made from puffed wholegrain brown rice and suggests eating them alone or with toppings.
- A plain, lightly salted cake can be considered as a base when you want to choose the topping separately.
- Read the pack’s per-cake nutrition before comparing its portion with products carrying a stated kcal-per-cake figure here.

Rice cake picnic questions
Is a rice cake automatically a low-calorie picnic lunch?
No. Kallo and Tesco each list a lightly salted product at 27 kcal per cake, whereas Kallo lists its milk-chocolate cake at 84 kcal. The number of cakes and any toppings also count towards the finished lunch.
Should I compare figures per 100 g or per cake?
Use both for different purposes: per-100 g figures provide a common comparison basis, while per-cake figures help you count the portion you will pack. The NHS notes that nutrition is given per 100 g and sometimes per portion, and that manufacturers’ portions can differ.
Do topped rice cakes need a cool bag?
They do if a topping is a food you would normally keep in the fridge. Food Standards Agency picnic guidance advises carrying such foods in a cool box or cool bag with ice or frozen gel packs.
How long can chilled picnic food stay out in extreme heat?
In extremely hot weather, the Food Standards Agency advises using food that has been out of the fridge within 2 hours. Keep normally refrigerated toppings cool while carrying and serving them rather than treating that time as a storage target.
Does gluten-free or vegan wording settle the allergy question?
No. Check the exact pack’s ingredients and allergy advice. Kallo describes its Lightly Salted cakes as gluten free and vegan-friendly but says they may contain milk, sesame seeds and soya; Tesco lists milk-containing ingredients in Snack a Jacks Sour Cream & Chive.
