When working on TV with food and beverages there are a few important tips to keep in mind:

• Take small bites! (Especially if  lines are to be delivered afterwards)
• There should be a change in expression or physicality from ‘before the tasting’ and ‘while tasting’, showing the product’s effect on the actor.
• This goes without saying, but actors should chew with their mouths closed, and not speak with food in their mouths!
