It's been yonks and yonks since I bit into a jam sandwich. In fact, I may have been about 10 and still in Kenya. The jam probably came out of a tin and instead of butter it was probably Blueband (which also came out of a tin). I remember that it was a real treat back then and I used to really savour my jam sarnies.
Today I cut off the crusts, I butter one side with Lurpack and the other with Bonne Maman Raspberry jam.
Mamma would shake her head at me BUT she would be smiling that knowing smile.
