Perilla (Kkaennip)

A mint-family herb used extensively in Korean (kkaennip, 깻잎) and Japanese (shiso, 紫蘇) cooking, though the Korean and Japanese varieties differ meaningfully in flavor. Korean perilla is larger, broader, more robustly flavored — with a combination of mint, anise, cinnamon, and something distinctly green that shiso doesn't have. Japanese shiso (both red and green varieties) is more delicate and floral.

In Korean cooking, perilla leaves are used as wrapping leaves for grilled meat (ssam), pickled in soy sauce and sesame oil, folded into rice, and used as garnish for noodle dishes. In the Borderless Kitchen context, perilla functions as an herb finish the way Italian basil does — added fresh at the end of a dish, never cooked, with enough flavor to redirect the dish's aromatic character.

The substitution works in both directions: basil in place of perilla softens the Korean edge; perilla in place of basil adds unexpected depth. Not interchangeable, but worth experimenting.
