Open these two Recipe cards, and you'll see they have the same structure:

Chilaquiles

help edit space_dashboard

Carnitas

help edit space_dashboard

You'll also see the same pattern when you create a new Recipe card.

Here's the structure rule that is used to template Recipes:

Recipe+*type+*structure

RichText :

{{+preparation time | labeled}}

{{+serves | labeled}}

{{+diet | labeled | link}}

{{+tags | labeled | link}}

{{+ingredients|titled}}

{{+preparation|titled}}

{{+discussion|titled; show:comment_box}}

help edit space_dashboard

{{+preparation time | labeled}}

{{+serves | labeled}}

{{+diet | labeled | link}}

{{+tags | labeled | link}}

{{+ingredients|titled}}

{{+preparation|titled}}

{{+discussion|titled; show:comment_box}}

You'll notice the structure nests cards with recipe information like preparation and cook time, number served, ingredients, etc.  When someone edits a recipe, they can edit those nested cards. (See sample recipe edit form.)
