Crisp, mild-tasting water spinach is a favorite leafy green enjoyed in Taiwan. When lightly sautéed, the hollow stalks retain a crisp texture that’s appealing enough for the finest banquet tables. While often simply sautéed with garlic, a touch of fermented tofu is sometimes added to provide a hint of savory flavor and a cloudy complexion to the liquids released from the greens. Fermented tofu is found in tiny cubes packed in small jars, and is extremely potent. Only a small dab needs to be used, mixed with some water, to gently flavor an entire dish of these greens.
One jar will keep forever in your fridge, ready to transform everything from sautéed greens to vegan "blue cheese" dressing.
