creative you don't have to be British to enjoy many of those foods. We're lucky enough to have an Irish pub about 15 miles from us that serves many of those foods in a most tasty manner. In fact, I enjoy many of the variations of mash (Colcannon, Boxty) with bangers. Just wish I knew where to source bangers to cook at home. This pub also has Scotch eggs. One of these days I want to make them at home.
MC my Mom used to make kidney stew several times a winter when I was a kid. Loved it! Then I found out what exactly a kidney was. Urp. Just the idea of organ meat...
Not to single out British fare, I had the same reaction when I found out that my much loved Polish soup czarnina was not, as my dear Great Aunt would tell me, made from solid chocolates but was instead duck's blood soup. Nanna NEVER got another Hershey bar from my stash again.
Bubble and Squeak has graced out plates here at home. We ran across it on our first visit to Williamsburg VA and bought the cookbook from there so I could duplicate many of the foods. That book has served me well for over 35 years.
