Yes, you can do that, I have successfully interrogated prisoners in the mixing bowl.
Do you know how to interrogate prisoners on the chair (I love how the torture is that they are spun around, wonder how they die from it)? It is the same thing, except you click on the mixing bowl.
The long explanation.
When you click on an enemy agent, a bar appears above his head with various options. Click on the handcuffs to capture him, you need a prison cell to do this. He will be knocked out and carried to the cell. Click on the prisoner, once in the cell, to bring up a new menu. You will want to click on the "Interrogation" button, with two figures. Then right click on the mixing bowl. If you did it correctly, a security guard should walk over to the cell and march the prisoner to the kitchen. If not, try again.
