Three sauces under the Sweet Mandarin brand name - Barbecue, Sweet Chilli and Sweet and Sour - went on sale at Chinese grocer Wing Yip last month after successful sales from the restaurant.
The sauces, which are all gluten and MSG-free, were originally made by owners Lisa and Helen Tse for sale to the restaurant's customers. Since securing listings at Wing Yip's four stores in Birmingham, Manchester, Cricklewood and Croydon, they have seen sales grow by 300 per cent.
"We sold out of the sweet chilli dipping sauce in just two days. A 300 per cent uplift is a very encouraging start to our partnership with Wing Yip and we look forward to growing our market share in the future," said Lisa.
The move sees Sweet Mandarin join the likes of Wahaca, Pizza Express, Carluccio's and independent restaurant Eat 17 secure listings for their branded products in retail outlets. Selling restaurant branded products can provide an extra revenue stream as well as increase brand recognition, operators say.
