For my taste it is sufficient to wrap every other scallop on the stick.
Use half a strip of bacon for each scallop you wrap.
Cook the bacon they way you normally would.
Crisp but not extra crisp and while the bacon is hot, wrap it around the raw scallop.
Put the bacon wrapped scallop on the stick and sprinkle with salt and pepper.
Chill.
Notes
Scallops are the most delicate of shellfish. If left to itself, it can be almost tasteless. It is also very lean. When teamed with bacon it creates a rich savory morsel, which is top on most people's list. Put them over on open flame and wow!
