Soy sauce alternative typically made from soybeans, salt, and water without wheat. Most brands are vegan, though verification recommended for specific products.
Tamari is made from soybeans (legumes), which are explicitly excluded from paleo. Even though it is fermented and contains minimal carbohydrates, the legume source disqualifies it.
