<\/a><\/p>\nBack in November I wrote about the photos I took of the Yacon plant in the garden showing the plant and the harvesting of the tubers – the post is here.<\/a><\/p>\n But what do you do with the tubers? – recipes\u00a0 are scarce. The book I found out about the plant suggested grating them for a salad – this was OK but but not very inspiring. I tried boiling them like potatoes but that didn’t work. I couldn’t find anything else about using this plant (although lots of uses for the commercially produced low calorie sweetener derived from this plant.)<\/p>\n Then it dawned on me. Carrot cake was originated (as far as I can tell) during WWII as carrots have a highish sugar content and they are used as a sweetener. Yacon is a sweet, low calorie tuber, so why not use it for a carrot cake but substitute the carrot with Yacon.<\/p>\n So I found a recipe and substituted the 8oz of carrots with 12oz of yacon – I increased the amount as yacon is quite watery – and baked a cake. Yes I made it (the first cake I have made for countless years); my wife thought I was mad.<\/p>\n But it turned out very well – we both couldn’t keep our hands off it which is why you only see half of the cake in the photo.<\/p>\n But where does the focus stacking come in? – this is the technical photography bit.<\/p>\n I have bought a new device to help take time-lapse, HDR and focus stacking image sets (a ‘Promote Controller’) and wanted to try focus stacking. Focus stacking is a technique for getting more of the image front to back in focus especially for close-up photography. So the new yacon cake (or the remaining half!) became the subject:<\/p>\n These photos are my first attempt at focus stacking. The first pair had a window behind the subject hence the bright highlights on the top of the cake. This second pair had the window behind the camera.<\/p>\n What have I learnt? The technique needs more practice and it is more difficult than it looks to take an effective photo of a cake.<\/p>\n More practice is needed!<\/p>\n","protected":false},"excerpt":{"rendered":" A bit of a mixed bunch in the title but they all came together.
