Calrose
What it is
A medium-grain rice that became the foundation of California rice culture and the default "sushi rice" for much of the Americas. Plump, oval grains that cook moist and slightly sticky.
How it's made
Developed at the Rice Experiment Station in California and released in 1948; the name combines "Cal" (California) with "rose," the rose group of medium grains. It transformed California into a medium-grain powerhouse and is now a whole family of Calrose-type cultivars.
Flavor profile
Mild, slightly sweet, tender, with gentle clinginess from higher amylopectin (amylose ~17–19%). Cooked grains hold together enough to be eaten with chopsticks and shaped by hand.
Culinary uses
The everyday sushi, poke, musubi, bibimbap, and rice-bowl grain throughout the US and beyond, because true Japanese cultivars were historically scarce abroad. Water ~1:1.25–1.5 (rinsed); cooks ~15 minutes plus a steam rest. Seasoned with vinegar for sushi.
Regional variations
Calrose is grown in California, Australia, and Egypt; Australian Calrose is a major export to East Asia and the Middle East. Numerous improved Calrose-type lines exist.
Cultural & historical context
Calrose enabled Japanese-American, Korean-American, and Hawaiian rice cooking on US soil, and is a quiet hero of diaspora cuisine: the rice that let immigrant communities recreate home food when imported short-grain was unavailable.
