Shelf life – the topic on everybody’s lips, the bane of many a chocolatier’s business plans, the thorn in the side of the display cabinets of bakers up and down the country. It’s a tough subject to tackle, and an even tougher one to get right, but with a little learning, you’ll be able to tailor your recipes to the amount of time you wish your sweet treats to be at their best.

There are many factors that can impact the shelf life of even the simplest of confectionery, but today, we’re going to focus on just one; tempering your ganache. Before we go into that, however, let’s recap the other factors affecting shelf life that you should also consider when developing your chocolate or bakery recipes.
Remember, there are a multitude of reasons why there’s no cut and dry answer to the question, “What will the shelf life of this bonbon be?”.

Ganache is a staple in the chocolatier’s and baker’s recipebook alike, and with many learning the microwave method from day one, tempering your ganache as a means of improving shine, consistency, and shelf life is a lesser known technique that you may want to consider implementing in your day to day activities. Essentially, you’re bringing down both the cream and tempered chocolate and combining them at a workable temperature. Here’s a recipe using white chocolate – this will have to be adjusted if using milk or dark.
You’ll need:
Step 1 – Pour the cream and invert sugar into a pan and bring to boil, combining as you go.
Step 2 – Once at boil, take off the heat and combine with butter using a spatula. Leave to cool to 32°C.
Step 3 – While your cream mix is cooling, melt and temper your chocolate using your preferred method.
Step 4 – Combine the white chocolate at around 30°C with the cream mix at 32°C with a spatula for around a minute, ensuring the sides are scraped.
Step 5 – Use a hand blender to finish combining the mix, breaking the surface at a horizontal angle to ensure no air is combined with the mix. If the noise of the hand blender increases in volume, this is a sign air has entered the mix. Simply stop and shake out the air bubble, or insert again as previously described.
If you’re making vegan, dairy-free chocolates, but still want a silky ganache filling, or you prefer to let your chosen chocolate shine without any added cream or fats, then a water ganache is the answer.
Water ganache has a shorter shelf life due to the high AW (water activity), compared to ganache made with cream and other shelf life-extending ingredients, such as alcohol and sugars. The recipe shared with us by expert chocolatier Paul A. Young in this video only includes dark chocolate, light muscovado sugar and water, and has a shelf life of just two weeks.
This recipe is incredibly versatile, as you can swap the water for any water-based, non-dairy liquid, such as black coffee, Earl Grey tea, fruit juice or red wine, and the character of your chosen chocolate won’t be masked by the richness of the dairy.
You’ll need:
Watch the video tutorial and follow along with to make your own quick and simple water ganache.
By tempering your ganache, you’ll get a firmer, more compositionally stable (and shinier) result, giving the mixture an extended shelf life. Of course, any other standard method of making ganache is perfectly fine, but if you want to really stretch the shelf life of your chocolate creations, then consider this method alongside other shelf-life-extending techniques and ingredients!
