Question: what is the difference between kale and sweet kale?
Answer: Red kale or red Russian kale has a very similar taste to curly kale but-you guessed it!- often has red-hued stems. The leaves are flatter than those of curly kale (resembling arugula leaves) and can be green or gray-green in color. Red kale is often considered the sweetest kale, which makes it perfect for eating raw.
