Recipe for Chemistry?

To make interpersonal chemistry,
You need:

Two or more unoccupied persons
With some similarity about them.

Three Cups of conversation,
and another cup of sauce.
Half a cup of mock impatience,
When the thread of chat gets lost

Three jokes, lightly seasoned
With cussing or a wink.
Half a stick of double meaning.
Don't go light on this, I think.

I shouldn't need to mention,
But preheat with a little tension
Sprinkle candelight to make it gleam,
and a soupcon of not-what-it-seems.

Place in a setting
With no getting
Away, but ideally
You still seem free.

Mix liberally;
Wait and see.
