Line the base of a 26cm or 24cm (base measurement) spring form tin with baking paper, and grease the sides well with coconut oil or light olive oil
If using small 12cm flan tins, grease and line with baking paper (with the smaller tins I allow the baking paper go over the sides a little to help lift out the cooked Siena)
Preheat oven to 150 degrees fan forced
Place the nuts and the fruit into a large bowl
Sift the flour, cocoa and cinnamon into the bowl with the nuts and fruit and stir through … push the mix to one side so there is room to pour the melted chocolate and hot honey/sugar mixture in … it is easier to mix these in from the side, going "up and under" with your spoon rather than pouring these two items on top and then trying to stir them in
Put sugar and honey into a small saucepan and heat over a high temp, stirring every now and then until the sugar is dissolved (I use the “simmer” hot plate on my range so that once I reduce the heat to “low” I know it won’t be too high a temp)
Once sugar is dissolved, stop stirring, and as soon as the mixture comes to a rolling boil reduce heat to the lowest simmer for five minutes (use your timer)
Whilst the sugar and honey is cooking, melt the chocolate … I do this in the microwave for convenience
Add the chocolate to the fruit and nut mixture just before you add the hot sugar and honey mixture (pour both of these into the space you have created to the side of the mixture in the bowl)
Working quickly stir all the ingredients together with your wooden spoon until you can no longer get your spoon through the mix
Using a thin scraper and your hands that you dip in water, work the mix around your mixing bowl ensuring all the ingredients are incorporated and no more flour is visible
Scrape the mixture into the large baking tin
Dip your hands in water again and push the mixture into the tin and flatten the surface lightly
NB: If making small cakes, still push the mixture into the large tin (no need to line the tin, but make sure you grease it well first with light olive oil so you can get the mixture out), then unclip the sides, cut mixture into four even pieces with your thin spatula, and with wet hands lift each piece, shape into a rough round, and press into your smaller containers getting the mix right to the edges (I usually weight each tin once the mix is in, and before I spread out with my fingers, to ensure I have an relatively even distribution of mixture, but that process is optional)
Bake 1 hour for large cake, and 35 minutes for small cakes (you can fit four small onto one baking tray)
Remove from oven and place tin onto cooling rack for an hour or so, then remove cake from container (leaving the baking paper on the bottom) and place directly onto cooling rack to get completely cold
Once cold, store in a freezer bag in a cool spot until ready to cut
If making small Siena, pack four, one on top of the other – still with the baking paper on the base – into a freezer bag until ready to cut
Leave for a few days before cutting
