scotch sour

When I'm out at a bar, I'll order a Whiskey Sour. As far as getting a good drink goes, it's a safe bet.
However, when I'm at home and get to play bartender, I serve myself a 'Scotch Sour'.
It's a bit more specific in terms of its construction. Here's how to build it:

Grab a tall glass and toss in three ice cubes.

Pour your FAVORITE sipping Scotch to the top of the ice cube stack.

Add a HUGE over-sized spoonful of frozen lemonade concentrate.

Stir.

Add two packets of Truvia (or any other sweetening agent).

Stir it up while adding Sprite (or 7-Up) to the top.

Sip with complete satisfaction.

[ NOTE OF CAUTION ]
Using a high end sipping Scotch, such as Oban, for a mixed drink
may not go over well with the guy who bought the bottle.
