If you are talking about Wordpress then you know you are using an online script written in PHP and there is no need to use ane additional software. You can publish using the available plug-ins that have been designed for such things. The entire database of plug-ins is accessible from the administration menu of your blog. When you will search for the grocery term, you will be presented with a list of grocery plug-ins available. I have checked and the first provided entry is available for your own needs. Click install on the right side and wait for the plug-in to finish installing then you can use it as a simple software.
