Pomegranates are very stubborn.
I'm stubborn, too, which is probably why I like them.
While a pomegranate may be stubborn, it's totally worth the time to juice your own.
To juice a pomegranate I recommend following these steps from Simply Recipes. I did and was able to extract enough juice to make a tasty salad dressing.
Mix together a few tablespoons of the pomegranate juice with a little squeeze of both a lemon and an orange. Mix in a splash of red wine vinegar. Whisk in about 2 tablespoons of olive oil. Drizzle just enough dressing to lightly coat the greens and gently toss it all together.
Add in some sliced apples and slivered almonds and toss again to mix. Sprinkle a small amount of salt and pepper over the top and serve.
