Oh eck, haven't got the hang of the quotation bit!!
Someone said in an earlier posting about the Victorian practice of taking the ice of the pond, and storing it in underground caves.
The point I intended to make was, that the Victorians did not have the benefit of electricity, refrigerators, ice-making machines, etc. But they were very innovative. Some of the ice would have been used around the churn to make ice cream. Even they would not have been stupid enough to have put a chunk in the G&T.
My grandad was a gardener in service, somewhat older that Harry Dodgson, who presented the programme. I was born 1944, but I can remember grandad, using his Victorian know-how to provide us with peaches, pineapples and grapes, in the most austere of post-war times.
I really think you should take the Victorian gardeners seriously. They achieved some fantastic results, albeit in the name of the man who owned the 'big house'!!
