Notes
Why shake a stirred classic. The traditional Boulevardier is stirred to keep it silky and spirit-forward. Shaking it here trades a little of that texture for more dilution and aeration -- a fair swap for a drink built for zero extra dishes, not for matching a bar program pour-for-pour.
The improvised lid. Any cup that friction-fits the rim will do, as long as both pieces are rigid -- a thin plastic cup flexes under the shake and lets go. A Hydro Flask tumbler with an aluminum Solo cup over it is the pairing that works best: the metal rim seats tight and neither piece gives. Press the cup on firmly with your palm, and hold cup and glass together at the seam. A loose seal is the only real failure mode here.
Rye vs. bourbon. The original recipe (and most modern versions) use either interchangeably. Rye's spice holds up better against Campari's bitterness, which is why it's the default here -- swap in bourbon for a rounder, sweeter pour.
Scaling for a crowd. Batch the rye, Campari, and vermouth in one bottle at ratio ahead of time, then build and shake tumbler-by-tumbler to order. Don't batch-shake more than one serving in a single tumbler -- a press-fit seal isn't rated for it.
