Who is this for?

The choice changes depending on whether you are sharing refreshments, selling packaged snacks or serving someone who needs ingredient information.

Hosts planning portions

If you are putting out a sharing bag, compare kcal per 100g before using the stated 25g or 30g serving as a guide to how much to offer each person.

Sellers offering packaged snacks

Original sealed packs retain their ingredient and allergen labels. If your stall operates as a food business or you repack food for sale, check the applicable registration and labelling requirements before trading.

Hosts serving guests with dietary restrictions

Check each pack rather than assuming corn-based chips have the same allergen information. Waitrose lists may-contain warnings for milk, soya, wheat and cereals containing gluten on Doritos Dip or Load Salted.

What should you check?

Start with a like-for-like energy comparison, then plan the amount served and check the current pack before offering it to anyone else.

PriorityWhat to checkYour needs
Energy Compare kcal per 100g on the exact product labels. Waitrose lists Doritos Dip or Load Salted at 471, Tesco lists Doritos Lightly Salted at 487, Waitrose lists Essential Salted at 489, and Sainsbury's lists its Tortilla Chips at 494 kcal per 100g. I want to compare the chips on the same basis, without treating 'lightly salted' as a calorie description.
Portions Check the stated serving weight as well as energy per serving. The compared labels use 25g or 30g servings; a sharing bag does not divide itself into those portions. If I am setting out a bowl for guests, I need to decide how much goes into each serving. I would also account for any dip offered alongside it.
Ingredients Read the current pack's ingredients, suitability statements and allergen declaration. Waitrose lists may-contain warnings for milk, soya, wheat and cereals containing gluten on Doritos Dip or Load Salted. Someone I am serving may need information about a specific ingredient; the fact that the chips are corn-based is not enough to answer their question.
Selling food If the activity is a food business, the Food Standards Agency says to register with the local authority at least 28 days before trading or starting food operations. Its prepacked-for-direct-sale rules also depend on how and where food is packed and sold. If I plan to sell rather than simply share snacks, I need to check which rules apply before opening packs or putting chips into smaller bags.

Common mistakes

  • Reading 'lightly salted' as 'low calorie'

    Tesco lists Doritos Lightly Salted at 487 kcal per 100g, while Sainsbury's lists its Tortilla Chips at 494 kcal per 100g. The flavour description does not tell you which has less energy.

    Compare the kcal per 100g figures on the packs instead of choosing by the flavour wording.

  • Comparing unlike servings

    Waitrose states 122 kcal for a 25g serving of Essential Salted Tortilla Chips and 141 kcal for a 30g serving of Doritos Dip or Load Salted. Those serving figures describe different amounts of food.

    Use kcal per 100g for the product comparison, then decide what weight you will actually serve.

  • Assuming corn-based means suitable for every guest

    Waitrose lists may-contain warnings for milk, soya, wheat and cereals containing gluten on Doritos Dip or Load Salted.

    Check the exact pack's ingredients and allergen declaration before offering chips to someone with a dietary restriction.

  • Repacking chips for sale without checking the rules

    For food that meets the prepacked-for-direct-sale conditions in England, Wales or Northern Ireland, the Food Standards Agency requires the food name and a full ingredients list with allergens emphasised.

    If you intend to repack chips or operate a food business, check the Food Standards Agency's guidance and ask the relevant local authority what applies to your stall before trading.

Brand and retailer references

These figures concern the named products, not every tortilla chip made or sold by each brand or retailer.

Doritos

The compared products include lightly salted chips and a larger Dip or Load sharing bag.

  • Waitrose lists Dip or Load Salted at 471 kcal per 100g and 141 kcal per 30g serving; Tesco lists Lightly Salted at 487 kcal per 100g.
  • The Dip or Load Salted label lists may-contain warnings for milk, soya, wheat and cereals containing gluten.

Sainsbury's

Its 200g Tortilla Chips provide a labelled plain-chip option for comparison.

  • Sainsbury's lists 494 kcal per 100g and 148 kcal per 30g serving.
  • Use the per-100g figure when comparing it with products whose labels specify a different serving weight.

Essential Waitrose

The Salted Tortilla Chips label uses a 25g serving reference and states that the product is suitable for vegans and vegetarians.

  • Waitrose lists 122 kcal per 25g serving and 489 kcal per 100g.
  • The 25g figure is a serving reference, not an individual pack; check the ingredients separately for a specific allergy.

M&S

M&S describes its 200g Lightly Salted Tortillas as corn-masa tortillas for serving with dips.

  • The product description identifies the pack size and lightly salted flavour.
  • For a calorie comparison, read the current pack's kcal per 100g figure and account for any dip served with it.

Questions about serving and selling

Are these tortilla chips low in calories?

Do not describe the four compared products as low-calorie choices: the labels published by Sainsbury's, Tesco and Waitrose put them between 471 and 494 kcal per 100g. You can compare their energy figures relative to one another, then consider the amount you will serve.

Should I compare kcal per serving or per 100g?

Compare kcal per 100g first because the stated servings differ between products. Then use the 25g or 30g serving information on the relevant label to plan how much you will put out.

Do I need to register to sell snacks at a car boot sale?

If your activity is a food business, the Food Standards Agency says to register with the local authority at least 28 days before trading or starting food operations. Check with the relevant local authority whether your particular activity meets that condition; do not assume an occasional event is exempt.

What changes if I put chips into smaller bags to sell?

If the food meets the prepacked-for-direct-sale conditions in England, Wales or Northern Ireland, the Food Standards Agency requires its name and a full ingredients list with allergens emphasised. Check how those conditions apply before repacking; an original sealed pack already carries its own ingredient and allergen information.

Are corn tortilla chips automatically suitable for someone avoiding gluten or milk?

No: check the exact pack before serving it. Waitrose lists may-contain warnings for cereals containing gluten, milk, soya and wheat on Doritos Dip or Load Salted Tortilla Chips.
