The ingredients in McCoy’s Flame Grilled Steak Flavour Potato Crisps include potatoes, sunflower oil, and a flavouring mix that gives the crisps their signature taste. The flavouring contains lactose (from milk), salt, dried onion, dried yeast extract, and flavour enhancers such as monosodium glutamate and disodium guanylate. The crisps also include maltodextrin, dried skimmed milk, citric acid, and paprika extract for coloring. These ingredients combine to create a full-bodied, savory snack with a subtle smokiness.

In terms of allergens, these crisps contain milk and may also contain traces of soya, gluten, and mustard. This is important for those with allergies or sensitivities to these ingredients.
