NUTRITIONIST INSIGHT

Yuzu kosho is a zero-calorie flavor bomb that can transform bland healthy foods into exciting dishes. The vitamin C and antioxidants from yuzu peel plus capsaicin from chilies provide modest health benefits. Use 1/4-1/2 teaspoon to add intense flavor without calories.

Myth Busters

MYTH #1: Yuzu Kosho Is Just Another Hot Sauce

TRUTH: Unlike vinegar-based hot sauces, yuzu kosho is a fermented paste with complex citrus aromatics from yuzu peel, providing unique floral-citrus notes alongside heat. It's closer to a flavor enhancer than a simple spicy condiment.

MYTH #2: Green and Red Yuzu Kosho Are the Same

TRUTH: Green yuzu kosho uses unripe yuzu and green chilies for a brighter, more pungent flavor. Red yuzu kosho uses ripe yuzu and red chilies for a mellower, slightly sweeter taste. Choose based on your dish and preference.

MYTH #3: Yuzu Kosho Has Significant Vitamin C

TRUTH: While yuzu fruit is rich in vitamin C, yuzu kosho uses only the peel in small amounts. A teaspoon provides ~2mg vitamin C (2% DV). It's a flavor enhancer with modest antioxidant benefits, not a vitamin supplement.

MYTH #4: The Salt in Yuzu Kosho Is Unhealthy

TRUTH: At 330mg sodium per teaspoon, yuzu kosho is high in salt. However, its intense flavor means you need less to season food, potentially reducing overall sodium intake compared to salting dishes directly. Monitor portions if hypertensive.

MYTH #5: Yuzu Kosho Must Be Refrigerated After Opening

TRUTH: Due to high salt content, yuzu kosho is shelf-stable, but refrigeration extends freshness and preserves volatile citrus aromatics. For best flavor, refrigerate after opening and use within 6-12 months.
