San Nicasio are handmade small-batch potato chips, made with Catalan potatoes, extra virgin olive oil and Himalayan pink salt (a marketing term for rock salt mined in Khewra Salt Mines, Pakistan). The olive oil used has the "Priego de Córdoba" denomination of origin. As of 2012, they are only available in salted flavour and two sizes, 40 g (1.4 oz) and 190 g (6.7 oz).
Cooking
The chips are slow cooked, unlike most other brand-name chips. According to owner Lopez this is "to prevent the formation of undesirable substances".
Pricing
In 2011, the product received press coverage on release in the United Kingdom due to the £4 pricing for the larger packet, almost double the market standard. Grocery magazine The Grocer asked "will British crisp-lovers fork out almost four quid for a new super-premium snack?", although it did not speculate on the answer to this question. The Rich Times stated that analysts "are as yet divided" as to whether or not a product at this price point "makes any sense".
