We're going to do a quick mini post for you as a nice little link from piping bags to nozzles.
This post is to explain couplers!! If you haven't come across a coupler before then you're missing out!!
Couplers, also known as adapters, are a cheeky bit of cake decorating equipment that don't look very exciting but can save you a lot of time and a lot of messing around.
To use a coupler you simply unscrew it and place the body of the coupler inside your piping bag. Then, on the outside of the bag you put your nozzle and screw it on!!
"And the reason for this is?" you ask!! Well when you are busy piping your blue stars, for example, and then decide that actually you want to now pipe blue dots you can simply unscrew the nozzle and change it over. Without a coupler the nozzle would be inside the bag and so you would have to empty the bag out (which is a messy job!) and change the nozzle and then re-fill it.
The standard sized coupler fits all standard sized nozzles. You can also find a large coupler that fits the larger nozzles.
Ok, so we admit it. This isn't the most thrilling of posts but it's sometimes these small bits of information that make all the difference so we hope you'll excuse us!!!
