Find either a Japanese market or a gourmet shop near you. Get directions and set out to find your yuzu.
Go to the store's condiment section to find the yuzu juice. It is often sold in a small bottle, although some gourmet shops may carry the larger bottle.
Look for a liquid inside that is yellowish-green and murky.
Pay attention to the price. Yuzu juice range from $30 to $40.
Purchase and take home to use in Japanese cuisine or substitute for any citrus juice in your favorite recipes.
