Thanks Gordon. That's something I'll try in my next Monte Cassino offering.

I use Rittenhouse on a reflex level, but Old Grandad, in it's higher proofs, isn't a mistake.

Exactly. Well said.

I prefer to deal in full ounce measurements. Guessing, or estimating, exactly what 3/4 oz. amounts to, under less than ideal lighting, adds to the chance for error. The Monte Cassino is a delightful drink, and using full measures will cause no harm. There's a lot going on in this cocktail, all of it subject to modification to suit various preference. Adding a little more rye, can aid in boosting a familiar flavor, to those preferring a whiskey forward cocktail. This is a very pleasant cocktail, with room for catering to a particular flavor. Keep it cold, and that will cover minor mistakes in the prep.
