I like to experiment when I make marmalade and I want to share this recipe with you because the addition of whisky gives a kick to the flavour and a smile to the face in the morning. I have made this recipe using blended and single malt whiskys so I will leave it up to you which one you will use.
If you want to make the marmalade a darker colour use 200g dark drown soft sugar, and the balance, 1.8kg of caster sugar. Also consider trying a muscovado sugar (about 200g and 1.8kg caster sugar) which gives the finished marmalade a deep flavour.
This is my favourite recipe. I make it for my Dad and Mother in law for Christmas,in a basket of home made treats. Delicious and always welcomed . - 02 Sep 2015 (Review from Allrecipes UK & Ireland)
