Oranges are not the only fruit, unless you’re making marmalade in which case, sorry Jeanette, but they pretty much are. I know that you can technically add tangerine, ginger, grapefruit and whatnot, but for me, the Seville orange reigns supreme because of its distinctive, tangy marmalade taste, though not before sugar has been added. I don’t know if you’ve ever accidentally eaten a bit of Seville orange thinking it was something other than a bitter cooking orange, but if you have you’ll understand the quote from Much Ado About Nothing:
The count is neither sad, nor sick, nor merry, nor
well; but civil count, civil as an orange, and
something of that jealous complexion.
If you want to make your own marmalade, and eat your sandwiches as Paddington Bear, intended, it’s pretty easy following this handy how to make marmalade guide from the BBC. Geeky literary quotes about Seville oranges and marmalade on the label are optional, but great fun.
