Donn's Mix is a tiki cocktail cordial that blends grapefruit juice with cinnamon syrup, typically in a two-to-one ratio.
Tart citrus over a warm, sweet cinnamon backbone, finishing with a faint bitterness from the grapefruit.
Serving as a combined souring-and-sweetening element, it is shaken with rum-based builds to add citrus acidity, spice, and body in one pour, dosed to balance the base spirit.
A homemade blend of fresh grapefruit juice and cinnamon syrup in similar proportion.
Donn's Mix combines fresh grapefruit juice with a spiced cinnamon-infused sugar syrup, prepared in advance and shaken as a single component rather than measured separately.
Because it contains fresh grapefruit juice, it is perishable; refrigerate and use within a few days.
