*I like to leave my slices out of the fridge for about 20 minutes before cutting so that the chocolate doesn't crack. Alternatively, if you live in a fairly cool climate, you may not even need to pop it back into the fridge after pouring over the chocolate, but rather set it aside on the bench until the chocolate has set.
TIPS FOR FREEZING SLICES
- you can freeze the slices as a whole or cut into individual pieces;
- wrap the slice in plastic wrap then wrap in a layer of foil and place into an airtight container in the freezer (these 3 steps will keep your slices tasting great!);
- slices with a soft filling (or cheesecakes) don’t tend to freeze well;
- slices kept in the freezer will taste best within the first month, but can last longer.
