For a maize-first snack, Walkers lists Monster Munch Pickled Onion at 98 kcal per 20g pack. Tesco lists 71 kcal for a smaller, 13.1g Skips Prawn Cocktail pack, but describes it as a tapioca snack containing maize flour. For half-term snacks, compare the exact portion, salt and allergens rather than choosing by the calorie figure alone.
Who is this comparison for?
Parents and carers planning half-term snacks
Individual packs make it possible to compare the portion being served, whether snacks are for home, an outing or a lunchbox. Check the weight as well as the calories: the packs discussed here are not all the same size.
Households checking allergens
Milk, wheat, soya and other allergen declarations can differ between snacks and flavours. A maize-based product is not automatically suitable for someone who needs milk-free or gluten-free food; check the current pack.
Shoppers looking specifically for maize snacks
Ingredient lists help separate maize-first snacks from other savoury snacks. Tesco describes Skips Prawn Cocktail as tapioca-led with maize flour, while Walkers’ Quavers Cheese ingredient list starts with potato starch and does not list maize.
What should you check?
Start with the individual pack you would serve, then check its ingredients and nutrition label; a multipack name alone does not tell you what each portion contains.
| Priority | What to check | Your needs |
| Portion calories |
Read kcal and weight for one inner pack, not just the multipack. Tesco lists 71 kcal per 13.1g Skips pack; Walkers lists 98 kcal per 20g Monster Munch Pickled Onion pack. The different weights matter. |
For an outing or lunchbox, I want to know how much snack one bag actually contains, rather than treating the smallest calorie figure as a like-for-like comparison. |
| Salt and labels |
Compare salt per pack and any traffic-light label alongside calories. Tesco lists 0.63g salt for its 23g Frazzles pack and marks that figure high. |
I'd check the label when choosing a savoury snack. In a Food Standards Agency and Ipsos Northern Ireland survey of 611 Northern Ireland respondents conducted from September to November 2024, 49% reported actively using traffic-light labels when shopping for food generally; that is not a maize-snack-specific figure. |
| Main ingredient |
Read the ingredient list if maize is important to the choice. Walkers lists maize first for Monster Munch Pickled Onion; Tesco lists tapioca starch before maize flour for Skips Prawn Cocktail. |
If I'm looking for a maize-first snack, a familiar shape or brand name would not settle the choice. |
| Allergens |
Check the exact flavour and current pack's ingredients and allergen statement. Product lines and pack formats should not be assumed to have identical declarations. |
For a child who must avoid a particular ingredient, suitability comes before a comparison of pack calories. A free-from label needs to match the specific requirement. |
Common buying mistakes
-
Comparing calories without checking pack weight
The 71 kcal Skips pack contains 13.1g, while the Monster Munch Pickled Onion pack listed by Walkers contains 20g. A lower per-pack figure also represents a smaller portion.
Compare grams, kcal and salt for the individual packs you are considering, then decide which portion fits the occasion.
-
Assuming every familiar savoury snack is maize-based
Tesco calls Skips Prawn Cocktail a tapioca snack containing maize flour. Walkers’ Quavers Cheese ingredient list starts with potato starch and does not list maize.
If maize is a requirement, use the ingredient list rather than the snack's shape or name.
-
Treating “baked” as a salt assessment
How a snack is prepared does not give its salt content. Tesco marks the 0.63g salt in its 23g Frazzles pack as high.
Read the salt figure and traffic-light label on the exact pack, alongside its calories.
-
Choosing a flavour before checking allergens
Maize snacks can contain or carry warnings for other ingredients, and an allergen declaration for one flavour should not be transferred to another.
Check the physical pack's ingredients and allergen statement each time, particularly when an allergy or intolerance determines the choice.
Brands and product lines to distinguish
Monster Munch
Walkers’ Pickled Onion 20g pack is a maize-first, individually portioned option.
- Walkers lists 98 kcal and 0.31g salt per 20g Pickled Onion pack.
- Check the flavour's milk, soya and precautionary allergen information; the Pickled Onion figures should not be applied to every variety pack flavour.
Smiths Frazzles
A bacon-flavoured corn snack for shoppers comparing individually packed savoury flavours.
- Tesco lists maize first and 111 kcal for the 23g inner pack in its 8 x 23g listing.
- Tesco marks its 0.63g salt per pack as high. Check the exact format and allergen declaration.
Wotsits
A cheese-flavoured maize snack available in different individual pack sizes.
- Walkers lists maize first and 123 kcal for its 22.5g Wotsits Cheese pack.
- The 22.5g figure does not apply to a 16.5g inner pack. Wotsits Cheese contains milk.
Skips
Tesco describes Prawn Cocktail Skips as a tapioca snack that also contains maize flour.
- Tesco lists 71 kcal for its 13.1g individual pack.
- Tapioca starch comes before maize flour in the ingredient list. Tesco lists 0.29g salt per pack, and the small portion is not directly equivalent to a larger maize-snack pack.
Tesco Free From
Onion Maize Snack Rings provide a product-specific free-from option to check against household requirements.
- Tesco labels this product gluten-free, wheat-free and milk-free.
- Tesco lists 124 kcal and 0.33g salt per 25g serving; its free-from labels do not determine its calorie figure.
Quavers
Quavers Cheese is worth distinguishing from maize snacks rather than grouping with them by texture.
- Walkers lists 86 kcal per 16g Quavers Cheese pack.
- Its current ingredient list starts with potato starch and does not list maize, so it does not meet a maize-snack requirement.
Joybuy snack options
These individually packed options include maize snacks and a popcorn multipack for half-term snack planning. Popcorn is a different type of corn snack; compare each product's own pack size and label rather than applying another product's calorie figure.

Walkers Monster Munch Variety 12 x 20g

Frequently asked questions
Are maize snacks automatically low in calories?
No. The figure depends on the exact product and portion. Tesco lists 124 kcal for a 25g serving of its Free From Onion Maize Snack Rings, while Walkers lists 98 kcal for a 20g Monster Munch Pickled Onion pack. Compare the serving weights as well as the stated kcal.
Does “baked” tell me how much salt a snack contains?
No. Baking describes preparation, not the salt figure. Read salt per pack and any traffic-light label on the product you intend to serve.
How should I check allergens in packaged maize snacks?
Check the ingredients and allergen statement on the current physical pack, including any may-contain warning. UK government allergen-labelling guidance says that prepacked food containing any of the 14 regulated allergens must clearly identify them in the ingredients list; a brand name or maize ingredient does not establish suitability.
Are Quavers Cheese a maize snack?
Walkers’ Quavers Cheese ingredient list starts with potato starch and does not list maize. Its stated 86 kcal per 16g pack may be relevant when comparing portion figures, but it should not be counted as a maize-snack option.
