Why This Works
Cold suppresses flavor — it's why melted ice cream tastes too sweet. A frozen daiquiri has to be built sweeter and more acidic than its shaken cousin, because at slush temperature everything registers at half volume. Taste after blending, always.
Using both lemon and lime is a quiet upgrade: lime gives the daiquiri its classic sharpness while lemon adds a rounder, sunnier acidity that flatters strawberries specifically. The rum alternative's cane sweetness underneath ties the fruit to the cocktail's Cuban roots.
The Alcohol-Free Swap
Alcohol-free rum keeps the daiquiri lineage intact — cane spirit and tropical fruit is the oldest partnership in the tiki canon.
