How to use vegetable juices to flavor your cooking

Why you need to learn this
One of our goals here at Prep School has always been to get you thinking outside your own box, to start thinking like a chef. Too many of us get into a rut, where we rely on the same old foods and standards that we've been making forever. Meatloaf Monday. Taco Tuesday. Whaleburger Wednesday. By taking something as simple as a vegetable — something we think of mostly as a side dish — and changing its form, suddenly we're presented with a completely new ingredient.
Moreover, as any juice fanatic can tell you, vegetable juices are very, very good for you. Getting more of them into your diet can only be a good thing.
The steps you take
Before we get started, a quick word on the difference between juices and purees, both of which involve taking a whole or cut up vegetable and pulverizing it. One difference is that, with juice, the solids are removed whereas with puree, the solids remain part of the final product. The other difference is that pureed vegetables generally are cooked first to make them easier to puree, whereas juices generally are extracted from raw vegetables.
There are several ways to get vegetable juice:
1. They sell it at the store. You can buy bottles of various juices and juice combinations, of course.
2. You can pass veggies through a juicer. Quality juicers produce great juices. If you're already into juicing, you know that you can juice just about anything, and you've probably been delighted, not only with the great flavors, but also with the vibrant colors of fresh juice. Imagine using these same great flavors and colors in supporting positions for dinner plates.
3. Even without a juicer, all you have to do is grate your vegetables or pulse them in a food processor. Then, place the pieces in some cheesecloth and wring out the juice. Not as easy or efficient as the juicer, but the results are good.
Obviously, there are exactly 2 bajillion vegetables on the planet, so we'll just mention a handful along with a few ideas. With any luck, that will spur your imagination to try some new ideas yourselves. (If you've got a good one, please share it with all of us at firstname.lastname@example.org or in the Comments section at the bottom of this article.)
What to juice
Sweeten ginger juice with sugar and add it to bubbly water for your own homemade ginger ale. Pouring a few drops of the juice into pureed soups like carrot or lentil will give it bright, spicy, gingery flavor. Use drops of ginger juice as you might soy sauce over Asian inspired stir-fries.
Use this sweet, bright orange liquid in place of milk for mashed potatoes. You'll love the color and creaminess. Enrich it with butter or, to keep it vegan, extra-virgin olive oil. Use carrot juice to replace some or all the liquid in baked goods or starches.
Beet juice is fantastic — and I'm one of the few people I know who dislikes beets. Deep purple and wonderfully sweet, try reducing it in a saucepan until it's slightly syrupy. Use a pastry brush to paint a broad swath of purple across a white plate as a striking background for your plated food.
Or, after plating your food, spoon droplets of the beet juice around as a decorative sauce. Or drizzle it over vanilla ice cream (with a bit of crumbled bacon, if you're really getting crazy). One note about beets: Wear rubber gloves to prevent your hands from getting stained.
