To tantalize is to tease with something out of reach, like Tantalus, whose food and water always pulled away.
King Tantalus was punished in the underworld by standing in water under a fruit tree. When he bent to drink, the water drained away. When he reached for fruit, the branch lifted out of reach.
Smelling a brisket that won't be ready for 14 more hours. Tantalizing.
