In Autumn I set out to make Sloe Gin (which I love) but -- couldny find any sloes in my usual secret places! That happens some years- - so I made Bramble Gin -- turned out well but - not as nice as Sloe!
However -- I also had a go at Quince Vodka - but refrained from adding the 'normal' sugar quantity, just put in a little. The drink is absolutely gorgeous - delicate but really pleasant on my palate. I would never think of sipping neat vodka normally but this is truly lovely!!
Definitely doing it again (as long as my pal's Quince tree produces; it is an old fashioned one, really difficult to make Quince jelly or paste from it, unlike more contemporary strains of the fruit.)

Re chopping the Seville oranges -- it is all part of the ceremony Jos! Whole process (chopping, steeping, initial boiling, adding sugar and second boiling etc) should take two days - in fact I know someone who takes 3 -- - -
My marmalade is really great, I love it (so do lots of others)
I do admit to using the food processor once I have halved / extracted juice and separated pips - partly cos tho I like the peel I don't like huge chunks!
