These are a wonderful dessert - you can store the figs in an airtight box in the refrigerator, although they are best served at warm toom temperature with a dollop of vanilla ice cream. B....r the diet!
Split the figs without cutting right through them and fill them with the walnuts. Press the figs together again to enclose the nuts. Arrange them in a single layer in a baking dish that just fits.
Dissolve the honey and cinnamon over a low heat. Pour on 250ml water (or even better white wine) stir well and bring to the boil. Pour the syrup over the figs and bake the dish, uncovered, in oven at 180 deg C(350 deg F) for 30-35 minutes or until all the liquid has been absorbed. Leave the figs to cool in the tin.
