What is the most appropriate way to handle multi-part recipes with Schema.org?
For example, a cake recipe that has two parts -- the cake batter and a frosting.
Should the two parts be separate recipe objects? Should they be grouped, without distinction, under a single recipe object? Or, is there a way to handle the separate parts under a single recipe (or other schema) object?
Here are a few relevant links:
