Retail meat and fish counters will soon offer cooking bags that can be used on the barbecue as well as in the oven.

Sira-Cook Barbecue Bags are heat-sealed by the butcher or fishmonger to allow retailers to offer leak-proof ready-to-barbecue packs.

Developed by packaging supplier Sirane, they will roll out in the next three to four weeks, although Sirane would not reveal which retailer they would launch in.

The bags will initially only be available from counters but in time shoppers will be able to buy them from retailers under Sirane’s Thinking-Cooking brand. Prices for the retail packs are likely to be £1.99-£2.99.
