You can easily double this recipe if you have a treeful of cumquats.
I tried the recipe and I must say it certainly has one major advantage - you don't have to wait 6 months to get a taste. While it's not quite the same with the liqueur from cumquats with brandy, I honestly liked it. - 27 Feb 2014
This was much easier than I thought and the proof is yet to be in the tasting but looks and smells lovely. K - 19 Dec 2015
