The “chickpea trail”, as described by Federico De Blasi, is a wonderful example of historical cross-border cultural and trading links founded on food (Tracing one delicious snack around the Mediterranean showed me that modern borders are absurd, 26 June). But such links need not be ancient and can sometimes be newly forged.
A few years ago, my family and I went on holiday to Denmark. In between Legoland and the airport, we stopped at roadside services for lunch. As we ate our chicken and chips, I spotted a man eating what appeared to be an enormous burger covered in gravy – using a knife and fork, as to do otherwise would have been logistically challenging.
