No ice just alcohol, tomato juice, worcestershire, etc…
Then pour into a glass with ice as needed.
Think it will work? (I’m not entirely sure what the alcohol would do to the tomato-y goodness if mixed for extended periods of time.)
No harm at all. Every couple of years I do just that and sit down on a Sunday morning to watch The Lost Weekend. When it stops being ironic and starts being sad I’ll know it’s time to cut back on my drinking.
Thanks. How do you get the measurements right? Eyeball it?
Everything by eye. Hey, it’s a pitcher of Bloody Marys, close enough is good enough.
The standard ratio is 1/3 alcohol to 2/3 mixer. Adjust to your level of raging alcoholism.
Lol. Thank you sir. 
If you can’t see through it, it ain’t doin’ you no good.
Or can’t marry it.
