The ingredients of McCoy’s Flame Grilled Steak Flavour Crisps include potatoes, sunflower oil, and a flame-grilled steak flavouring mix. The flavouring is made up of lactose (from milk), salt, dried onion, dried yeast extract, flavour enhancers like monosodium glutamate and disodium guanylate, as well as potassium chloride. Other ingredients include maltodextrin, dried skimmed milk, citric acid, and paprika extract for color. The combination of these ingredients creates a rich, smoky, and savory taste that closely resembles the experience of flame-grilled steak.

In terms of allergens, these crisps contain milk and may also contain traces of soya, gluten, and mustard, so they are not suitable for individuals with allergies to these ingredients.
