This cake was an experiment to test the quality of the freeze dried fruit chips sold by Waitrose. Their description suggests they are for cake decoration, but I wanted to see how well they kept their flavour and colour when baked.
I used a 2 egg cake mixture, with Madeira cake proportions - ie a slightly higher proportion of flour than a Victoria Sandwich mixture. To this I added 100g of plain chocolate chips and the whole pack of freeze dried raspberry pieces (only 10g). This was baked for about an hour at 180C in a small loaf tin.
As you can see, the raspberry pieces kept their colour, and the flavour was pretty good too. This is a good way of adding raspberry flavour without the complication of how fresh fruit will react in a cake mixture. However, at £2 for a small 10g pack of fruit, it's quite an expensive addition, particularly as flavour extracts are becoming easier to find.
