For a car boot sale refreshment with a stated 27 kcal per cake, start by comparing plain options such as Tesco Lightly Salted and Kallo’s lightly salted or organic unsalted rice cakes. Flavoured cakes offer a ready-to-eat alternative but have different serving sizes and ingredients; check each pack’s calories, allergens and storage instructions, particularly if you plan to sell or share them outdoors.
Sealed packs keep the manufacturer’s ingredient and allergen information with the cakes and require no topping preparation at the stall. Compare the stated calories per cake if you want to describe individual portions clearly.
The calorie figure for one cake or snack is a practical starting point. Tesco Groceries lists 27 kcal for its Lightly Salted Rice Cake, while its listings for selected Snack a Jacks jumbo flavours state 37 kcal or 50 kcal per snack; serving weights differ too.
Check the exact pack rather than assuming a rice-based snack suits everyone. Kallo lists precautionary milk, sesame and soya information for selected cakes, while some flavoured products contain milk or soya ingredients.
Start with the labelled portion, then check ingredients and the conditions in which the cakes will be offered.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per cake | Compare the labelled kcal per individual cake or serving, then its weight. Tesco Groceries lists 27 kcal per 7.2 g Lightly Salted cake and 37 kcal per 9.7 g Snack a Jacks Sour Cream & Chive snack. | I want to compare what someone will actually take, without treating differently sized cakes as identical portions. |
| Flavour and toppings | Check whether a cake is plain, flavoured or coated. If adding a topping, assess the finished snack rather than using the base cake’s calorie figure alone. | Some visitors may prefer a ready-flavoured cake; others may want a plain option. I need to keep those choices clearly distinguished. |
| Ingredients and allergens | Read the exact pack’s ingredients and precautionary statements. Kallo’s Organic Unsalted cakes, for example, carry a milk, sesame and soya precautionary statement. | I cannot assume a rice-based cake is suitable for everyone, especially when offering snacks to people with allergies. |
| Outdoor storage | Follow the pack’s storage directions and check how opened packs should be kept. Marks & Spencer says to store its milk-chocolate rice cakes in a cool, dry place away from sunlight. | For an exposed stall, I want packaging and storage arrangements that let me follow the chosen product’s instructions. |
Portions differ: Tesco Groceries lists 27 kcal for its plain Lightly Salted cake, 37 kcal for Snack a Jacks Sour Cream & Chive and 50 kcal for Snack a Jacks Caramel.
Compare calories per stated cake or serving alongside its weight before treating two products as interchangeable.
Marks & Spencer lists 481 kcal per 100 g for its milk-chocolate rice cakes and 386 kcal per 100 g for its lightly salted cakes. Those per-100 g figures compare calorie density, not the calories in an individual cake.
Check the coated product’s own portion information and ingredients, and present it as a separate sweet option.
Removing cakes from their packaging can separate them from ingredient and precautionary allergen statements. The Food Standards Agency and Food Standards Scotland say food businesses must provide allergen information for prepacked and non-prepacked food.
Keep the original information accessible. If preparing or repacking cakes for sale as a food business, check how to provide accurate information for the food you offer.
Marks & Spencer instructs customers to store its milk-chocolate rice cakes away from sunlight, a condition worth planning for at an outdoor stall.
Follow that product’s storage instructions or choose an option whose storage requirements you can meet.
These examples show how particular product lines differ; check the current pack for the variant you choose.

A savoury ready-flavoured option for the refreshment table. Tesco Groceries’ listing for Snack a Jacks Sour Cream & Chive Jumbo Rice Cakes 117g identifies milk in the flavouring and gives further precautionary allergen information; check the exact pack before offering it.
Start with the labelled calories per cake or stated serving, then check its weight. Tesco Groceries lists 27 kcal per Tesco Lightly Salted cake, 37 kcal per Snack a Jacks Sour Cream & Chive snack and 50 kcal per Snack a Jacks Caramel snack. Per-100 g values answer a different question: they compare calorie density rather than the portion someone takes.
No; read the exact pack’s ingredients and precautionary statements. Kallo says its Organic Unsalted rice cakes may contain milk, sesame and soya, so a plain appearance does not establish suitability for a particular person.
If your activity is a food business, Food Standards Agency guidance for England, Wales and Northern Ireland and Food Standards Scotland guidance require registration with the local authority at least 28 days before trading or opening. Whether your particular car boot sale activity is a food business depends on its circumstances; confirm that with the relevant local authority before selling.
If you operate as a food business, you must provide allergen information for both prepacked and non-prepacked food, according to the Food Standards Agency and Food Standards Scotland. Keep accurate information for the cakes and any toppings, and check the applicable requirements before changing how the food is packaged or served.
Follow the instructions on the chosen pack. Tesco specifies cool, dry storage for its lightly salted cakes and an airtight container after opening. Marks & Spencer also says to keep its milk-chocolate rice cakes away from sunlight.
