Scottish Marmalade?

[ThistleDown]

I suppose, with a heated greenhouse, sour oranges could be grown in parts of Scotland...

No, that's not how it should be, Ted. Sour Saville oranges were imported to Dundee and from them that unbeatable Dundee marmalade was developed. But those same oranges, grown in greenhouses local to Dundee, do not result in the same magnificent breakfast condiment. Grow the crop where it is best grown, transport with integirty and assemble the ingredients where they can be best assembled.

Or eat only what can be grown within a hundred miles of you.

And Ali, shame on you for going away on holiday and not making provision for your strawberries Tch tch (judge judge)
