WHY IT'S KETO-FRIENDLY
- Potent flavor = very small serving sizes (~1 tsp–1 tbsp), keeping carbs low
- Per 100g ~5–6g net carbs, but typical use is a fraction of that
- Choose sugar-free, traditionally brewed options; avoid sweetened blends
- Tamari is a good gluten-free alternative; coconut aminos are sweeter and higher carb—use sparingly
- Track macros if sauces/marinades add up
HEALTH BENEFITS
- Rich umami peptides can boost meal satisfaction
- Traditional fermentation yields bioactive compounds (not a probiotic after pasteurization)
- Adds depth to protein- and fat-forward keto meals, improving dietary adherence
- Trace minerals present, but sodium dominates—use mindfully
PREPARATION SUGGESTIONS
BASIC USAGE
Splash into stir-fries, scrambled eggs, or sautéed greens for instant umami.
FLAVOR ENHANCEMENT
Whisk with sesame-oil, grated ginger, and garlic for a quick finishing sauce.
MARINADE BASE
Combine with olive-oil, vinegar-apple-cider, and chili for steak or salmon marinades.
DIPPING SAUCE
Mix with wasabi or a little mayo-avocado for a creamy, low-carb dip.
SEASONING AGENT
Add a teaspoon to broths and pan sauces to round out saltiness with umami.
FINISHING TOUCH
Drizzle lightly over shirataki-noodles or zucchini-noodles just before serving.
