Aldi crisp packet contains only a single potato.

Aldi’s reputation could be in tatties after a customer opened a packet of crisps bought in store and found nothing but a whole potato inside.

But at least the budget supermarket chain proved it uses natural ingredients when Richard Bootman discovered the unpeeled spud in some Snackrite steak and onion crisps on Monday morning.

“I picked it up and it was airtight so I didn’t question it,” the 25-year-old, from Mildenhall, Suffolk, told BT.com.

“At first I thought it was a ball of soggy crisps. When I realised what it was everyone in the office laughed – we couldn’t believe it.”

The architectural designer was at his office desk when he made the unusual discovery in his mid-morning snack, bought from the Aldi store in Brandon, Suffolk.

The Snackrite crisp packet promises 100% British potatoes – and even features a photo of them on the packet – but despite this, the potatoes are obviously meant to be made into crisps before they are sold.

“It is likely I will buy them again, brand doesn’t bother me with crisps,” Richard added.

“But I will feel up the pack before I open them.”
