a) I want to put fresh fruit, and I want to be able to taste the texture of the fruit:- so I want whole fresh berries in the cake
b) the fruit shouldn't change the texture of the cake:- the problem with putting whole berries in any cake is that while the cake bakes, the berries explode while the cake is baking. So, this changes the consistency of the cake around the explosion, which makes that part soggy. Usually, it's fine. You just bake it a little longer, but the other parts are dry
c) I want to put lots and lots of fruit:- The problem with increasing the fruit is again more uncontrolled liquid seeping from the fruit into the cake, which makes it more soggy
Recipe is after the jump, but if you aren't bored yet, here's a somewhat technical explanation on how I got all of this done
So, to solve that problem, I had to take the juice out of the fruit without changing the texture of the fruit and also soften the fruit before it goes in so it doesn't explode. Sure, I could have just mashed the berries to extract the juice, but that would have changes the texture of the fruit too much. Besides, I have never tried to juice strawberries. Instead, I used a process called maceration. No, I didn't make the fruit dance and sing "Hey Macerena!" Maceration is a process by which you soften the texture of the fruit using it own's juices. You coat the fruit with sugar and put it in a wire mesh. The sugar sucks the juice out of the fruit and the juice gets filtered by the wire mesh. The process needs time and temperature to work. If your fruit is right out of the fridge , it will take longer than if it was at room temp.
