Scotch eggs are another favourite of mine that I can no longer enjoy since being diagnosed with coeliac disease., however, I have combined my two favourite scotch egg recipes and developed a whole new gluten free version...As usual ordinary breadcrumbs and sausage meat can be used if making a non gf version.
The double dipping adds an extra layer of breadcrumbs and therefor more crunch. To make the whole process a little less messy, try placing sausage meat mixture portion on some Clingfilm, flatten it out slightly and use the Clingfilm to cover the egg in the sausage. For the seasoning, simple salt and pepper works fine, however, I always use my own seasoning mix recipe #440608.
For a healthier alternative try omitting the frying and cook completely in the oven, however, don't forget to increase the cooking time an extra 5 mins to compensate.
