This is more than a dessert: in Lebanon it is traditionally prepared to celebrate a birth and also for Christmas (because baby Jesus). Ground caraway and even aniseed are not regular fare in Western supermarkets but you’ll find it in spice shops, Middle-Eastern shops, and if all else fails, try eBay, or just grind the whole seeds, which seem to be more common.
I’ll admit that this is not my favourite, but I love making it for friends who just had a happy event, and it is meant to be good for the mother after giving birth, with all these energy-packing nuts.
