Do not see the option to add recipes

This part was confusing to me too at first. The options page could use a line of text saying what to do next.

The plugin adds a new button to your toolbar.
To create a recipe, create a new post or page, then click the Recipe Card – Insert Recipe button on the toolbar, an editing window will open.

Create a post as if it were a normal blog entry.

In your WYSIWYG editor you’ll see a new icon alongside the Insert Link and Align icons etc…

The icon looks a bit like a cross-section of an onion and when clicked it’ll activate the recipe editor inside the normal text editor
