So I thought you might like to see my post about them from 2012 - and if you're very quick you might be able to find some. Not outrageously dear, mine were $7.95 a kilo and I only needed four, which cost me less than $4 (though I did have to buy the dessert wine as well). Cooking them as a dessert is really easy - you just have to stay vigilant so as not to overcook them and not to reduce the syrup to a sticky mess. The colour is incredible and the taste is uniquely delicious.
