Annie, as you know the River Tay runs through Dundee. That is where my husband was born and grew up and he often tells me of the days when he went berry-picking in the fields around Dundee during the school holidays (and sometimes instead of going to school!) I used to think he was making it up calling the berries TAYBERRIES and that it was just a local term for raspberries because I had never heard of them but like you , I GOogled it and found that they are quite new, was it the early 1960’s they came into being? Now I know how delicious they are! Actually we don’t see them down here very often, certainly not in the supermarkets anyway.
By the way, we are still thinking of coming up your way but not decided which week yet, the weather has been so poor it has not encouraged us to make any plans.
