Quarter Parts? – Cocktail Flow - Drink Recipes Review

Looks like a fairly robust compendium, whiskey choices aside (That whole rye vs. Canadian question is really a matter of taste, no? I personally lean toward VO in a cocktail....) What I wonder is what derfwad wrote recipes with quarter parts?! Not having a ml-graduated flask in my bar, I tend to mix martinis 4-to1, not 3-3/4 to 3/4. Really. Otherwise, a useful tool.
