Here's the "recipe" I used:
1 lb fresh cranberries
750 mL vodka
Chop cranberries in food processor until coarse
Combine cranberries and vodka
Cover and let stand for two weeks
Strain with fine mesh sieve into bowl; discard solids
Make a yummy cocktail!
*Disclaimer - I've never done this before and ours still has another week to go, so I can't say how great it is yet. The vodka is bright red at this point and it has taken some mighty will-power to not sample just a little bit!
