### The maths of marmalade

Jan. 19th, 2014 03:08 pmI use a lot of different jam recipes and don't have a particular formulae in my head about fruit to sugar rates or the pectin level of every fruit. So when I got home and worked out that I needed for every 1.3KG of oranges, 2.6KG of sugar to counteract the bitterness of the Seville oranges. In general and a fact I have now committed to remember, is that the jam/sugar ratio is about even.

I managed to palm off 2 * 1kg boxes of oranges on to understanding friends and very soon the final batch of seville marmalade will be jarred.

Next year I will buy 3kg. I blame this year's over purchasing on the fact they were labelled as one of my favourite Waitrose brands - 'cooks ingredients' which if I buy them, makes me a cook. Stands to reason.

Jar of marmalade anyone?
