Thermal Cooking Bags

Energy Saving Thermal Cooking Bags

Due to rising energy costs, many households need immediate, dignified & sustainable solutions to help reduce fuel costs & access nutritious food…

The Larder has teamed up with The Sewing Rooms social enterprise in Skelmersdale to supply energy-saving SewFab thermal cooking bags to our Kids in the Kitchen families and our trained Food Champions, to demonstrate how to use this energy saving bag to cook hot nutritious meals, including recipes and vouchers for fresh, seasonal and easily accessible value-for-money ingredients.

The Larder & The Sewing Rooms

The Larder’s Food Champions will be delivering workshops across Lancashire demonstrating how use the thermal cooking bags, including support and learning around freshly prepared food from ingredients sourced locally, understanding seasonality and nutrition.

The thermal cooking bags act as a slow cooker without using electricity. All ingredients are placed in a pan and brought to the boil for just 10 minutes. The pan is then wrapped in a blanket or towel and placed in the bag which uses the retained heat to cook, thus drastically reducing kitchen fuel costs.

…I have to admit I was sceptical of the cooking bag but it totally surprised me, everything was tender and soft after 3 hours, we will definitely use it again. Thank you…

The SewFab energy saving bags are both versatile & climate friendly:

  • Saves £££s on home fuel costs
  • Uses Heat Retention (no fuel, plug or batteries)
  • Handmade from high quality roll end fabric in Lancashire
  • Portable
