Hey Guys, I realise that there are probably one million and one topics/threads/conversations on ganache on here and I've scoured the site looking for an answer, but haven't found anything that specifically covers this topic. So, I'm no chocolate/ganache expert by any means, but I just recently discovered fruit ganache - I had no idea I could make ganache with literally fruit puree and chocolate....no cream! So I made a bunch of fruit ganaches to fill some macarons that I made, and they were fab, however I also want to use them in my cakes (wedding/birthday cakes). My problem is that once my cakes are filled, they get covered in a layer of standard white, milk or dark ganache and then they don't go back in the fridge - they are kept at room temperature until they are served. My question is about shelf stability. I know that my standard recipes for milk, white and dark chocolate ganache are absolutely fine at room temperature for a good long time, but what about Fruit Ganache?? To give you guys an idea of what I am using, the recipe I used was equal weights of chocolate to fruit puree - I melted the chocolate over a bain marie and heated the fruit puree until hot, but not boiling, then combined both together. At these ratios, the firmness was probably slightly softer than I would prefer, so I do intend on decreasing the fruit puree amount, but it was still lovely. I understand this might not be an easy question to answer, having read about water activity and how it varies depending on water and fat content etc, but any information you guys have would be greatly appreciated. Thanks, Jo.
