Layer not rendering correctly I've been following BlenderGuru's tutorials on making a donut and cup.  

I've gotten right to the end and now when I click 'Render Image', I don't get the icing:



The particles (sprinkles) are displaying, but not the pink icing.  I cannot figure out why.

The blender file is here:

And a screenshot of Blender:


Can anyone help me figure out why?
I guess you need to select your icing, then go in the Properties panel > Particles > Render and  enable the Show Emitter option.
