Japanese Shiso Perilla Herb Applications Red and Green Varieties

Nationwide Japanese cultivation; summer peak season; traditional in Japanese culture for over 2,000 years

Shiso (Perilla frutescens var. crispa) is Japan's most essential culinary herb — used raw, fried, pickled, and fermented across virtually every cuisine format. Two primary varieties define different applications: ao-jiso (green shiso) with its bright, slightly mint-anise-basil aromatic profile; aka-jiso (red shiso) with a more bitter, earthy, tannic character used primarily in shibazuke pickle and umeboshi production. Green shiso applications: chiffonade as sashimi garnish (providing both visual freshness and aromatic contrast); whole leaf as tempura base (chiso no tempura); blended into shiso ponzu or dressings; layered in rolled sushi (tekkamaki variation); whole-leaf wrapper for karaage; minced into tsukune (chicken meatball); incorporated into pasta (wafu shiso pasta). Red shiso: dried and ground into yukari (salty-tangy shiso seasoning for rice balls); used in umeboshi production where it contributes the red colour (shiso umeboshi vs 'white' umeboshi without it); shibazuke pickle's vivid purple-red colour comes from red shiso. Shiso's aroma is produced by the compound perillaldehyde — unique to the species. Fresh green shiso chiffonade for sashimi service is one of the three essential sashimi garnishes alongside daikon ken (julienne) and shiso blossom (hana-jiso). Premium shiso is grown in summer — the aroma is most intense in hot-weather harvests.

Green shiso: bright, mint-anise-basil with distinctive perillaldehyde freshness; red shiso: bitter, earthy, tannic with deeper aromatic complexity
