Making the plate and bowl

 

To make the plate, I took a cone and deleted the top. I created the inside of the plate and used cap to close the gap.

To make the bowl, I created a cylinder and modified the shape to make the bowl. I then cloned the bowl, scaled it to make it smaller, and used the boolean tool to remove it from the inside.

I finished it using a meshsmooth modifier, and a semi-transparent texture.
