What is it?
Red cabbage is exactly what it sounds like. While it isn't as exotic as a lychee or Chinese broccoli, it wasn't something I ever ate growing up in Southeast Texas, so it is exotic to me. Until later in life when I experienced some tart, sweet and savory red kraut at a German restaurant, I'd never had the urge to experiment with the stuff.
Apparently, red cabbage contains pigments called anthocyanins that possibly have cancer-prevention properties, improve brain function and aid in keeping your heart healthy. Red cabbage has 36 different types of anthocyanins, which equals a healthier cabbage than the green stuff.
The leaves are slightly sweeter than green cabbage and will need to cook longer, because red cabbage is picked at a later stage of maturity than its paler cousin.
How is it used?
Red cabbage is a popular vegetable in Germany, where it's braised with broth, vinegar and sugar to make a sweet and sour dish that goes well with schnitzel, bratwurst, spatzle and potato dumplings. It's also used raw in slaws and salads (sometimes just for the color) and often prepared with apples, pears, applesauce, onions and even spices like cinnamon because of its natural sweetness.
Weird/fun fact - if you add baking soda, the cabbage will turn a bluish color. In Bavaria, Swabia and Franken, Germany, after these ingredients are added, it's called "blue cabbage" (Blaukraut) because of its unique hue.
Where can I buy it?
Any grocery store in the city.
