This is not really a recipe but the leftovers of making 'membrillo' or quince paste (see our recipe http://www.mumandsons.com/2011/10/quince-paste-membrillo.html) which we made last week. The membrillo came out so well this year that I decided to buy a quince tree (which I am yet to plant)
Do not through away the liquid from boiling the quinces. Just mix it with water (2 parts of quince liquid for 1 of water) add a tablespoon of honey for each litre of liquid (or to taste) and the juice of half a lemon. Boil it all together and let it simmer for 5 minutes. Let it cool down and add some mint leaves before you drink it. Really nice.
