Rainbow Swiss chard is distinguished by its bouquet of wrinkled, slightly savoyed rich green and bronze leaves and bright colored stems. The leaves grow upright and tall from a dense rosette of ribbed stems in a myriad of colors including gold, pink, orange, purple, red, and white with bright and pastel variations. Rainbow Swiss chard is not unique from other chards in its subtle earthy flavors along with slight notes of tang, due to its betalain pigment content. The leaves are succulent and tender when young, the stems, fibrous and sometimes bitter and inedible.
In the culinary world, Rainbow Swiss chard is used as a salad green and a leaf vegetable, making it a versatile ingredient in the kitchen. It can be used both raw and cooked; cooking will give the leaves a milder flavor. Chard, in general, is used as a substitute for spinach and in tandem with other hardy greens such as kale, leaf mustard, and collards. Complementary ingredients include citrus, garlic, tomatoes, peppers, olive oil, grains such as rice and barley, artichokes, beets, roasted meats and chicken, cream, cheeses such as pecorino and parmesan, and herbs such as basil and arugula.
Place chard in a plastic storage bag and wrap the bag tightly around the chard, squeezing out as much of the air from the bag as possible. Place in refrigerator where it will keep fresh for up to 5 days. If you have large batches of chard, you can blanch the leaves and then freeze them.
