Make | Grandma’s Coffee Biscuit & Nut Slice

Recipe for milk coffee biscuit and nut slice

I was very close to my grandma, spending a lot of time with her and grandad as a child and also in later life. I have 10 years worth of beautifully handwritten letters, carefully bundled in a vintage suitcase, full of family news and the goings on of everyday life back home while I lived in London. It made sense to share Grandma’s rustic slice with you this Mother’s Day. Simple and full of so many memories. Enjoy x
