Use sparingly on keto. Prepared wasabi paste is mostly horseradish + starch + sorbitol/sugar—~40g net carbs per 100g—but a realistic dab is tiny (~2g per teaspoon), so it contributes minimal carbs.

WHY TO LIMIT IT ON KETO
- Intense heat and flavor means tiny portions go a long way
- Feasible on keto when limited to pea-sized amounts with sashimi or low-carb dishes
PREPARATION SUGGESTIONS
SASHIMI CONDIMENT
Serve a pea-sized dab with salmon or tuna sashimi (skip rice) and tamari.
