Instead of using a slow cooker you can use a new type of slow cooker called a ‘wonderbag’.
It’s insulating materials let you slow cook food without adding to your gas or elecricity bill.
Depending on the recipe, you’ll need to cook your dish on the hob first, but only for a short time. Then pop your cooking pot into the drawstring bag and leave it to finish cooking. Brilliant for camping with.
