Daikon oroshi is a condiment made of freshly grated daikon (Japanese white radish). Daikon oroshi is known to help with digestion, and is commonly eating with meat, fish and fried foods.
Daikon is an excellent source of digestive enzymes, which are more easily absorb when the raw daikon is grated. Grated daikon is also used to subdue fishy odor from both raw and cooked fish. It is typically served on top of a dish or on the side. Soy sauce is often poured on top, but it can also be mixed into other sauces like tempura sauce or ponzu.
