My recommendation is to start in a parking lot (as someone else suggested) and then get the trainee to be able to start the car by just releasing the clutch gradually, without giving the car any extra gas. The idea is for the person to learn at which point the clutch engages the engine to the wheels and have a good feel for that before they start applying gas. (I guess that is what an earlier post referred to as "feathering the clutch". )

Then have them start gradually applying a little gas as they release the clutch.

The purpose of the above approach is to avoid the car lurching forward, stalling, lurching, etc...while the passengers try to avoid whiplash.
