Whole Foods had one of their small sample kits of purple barley a couple of months ago, Jenise. They printed out a recipe for Tabouleh, and I used it with a main course salad.
Worked pretty well and it sure was pretty. I didn't notice any difference in taste from normal barley, though.
Purple Barley Tabouleh
Serves 4–6
* 1 cup purple barley
* 2 cups chopped tomatoes
* 2/3 cup finely chopped scallion, green and white part
* 1 cup finely chopped parsley
* 1/2 cup finely chopped mint
* 1 TB grated lemon zest
* 3 TB freshly squeezed lemon juice
* 1/4 cup extra virgin olive oil
* sea salt, to taste
* ground pepper, to taste
Bring 21/2 cups of water to a boil in a heavy saucepan. Stir in barley and bring back to a boil. Reduce heat, cover and simmer over low heat until tender, about 1 hour. Rinse with cool water, drain and set aside. In a large bowl, combine tomatoes, scallion, parsley, mint and lemon zest. Toss in well-drained barley.
Whisk lemon juice with olive oil and season with salt and pepper. Drizzle over salad and toss to combine.
