Bad risotto

I have had two bad risottos recently, both in restaurants. One had too much lemon oil added at the end, and the other was missing the finishing touch of truffle oil that would have given it flavor.

Even if the chefs had been skilled in adding their flavored oils, the risottos still would have been one-dimensional. Risotto, like most complex dishes, requires layers of flavor cooked into the food. The rice is first turned in olive oil, butter and wine, then cooked gently in a well-flavored stock. A few vegetables can be added for color and texture. I sometimes grate some parmesan or lemon rind over at the end, but that's an extra layer, not a required flavoring.

Vary the flavors in this simple technique to make Asparagus Risotto or Corn Risotto - two of my favorites.

I think the trouble with both restaurant risottos was the lack of flavor in the vegetable broth. Few restaurant chefs know how to make a good vegetable stock - the essential basis for an excellent vegetarian risotto. Instead they rely on flavoring oils and end up with at best a one-dimensional flavor, at worse something inedible.

The best vegetable stocks are made by roasting the vegetables before boiling them - just as you would roast bones when making a meat stock. Add to this some dried mushrooms, and a little soy sauce to get that umami, and you have a great stock, suitable for the best risottos, soups and stews.

I love this stock from Fresh From the Vegetarian Slow Cooker by Robin Robertson, an excellent source for stews and soups that are ready and waiting when you get home from work.

Once the vegetables are roasted, the stock bubbles away without me. When it's done, I store it in 2-cup containers in the freezer, ready to make delicious meals.

The parsnips add another dimension to the stock, and I make many batches during parsnip season. However, it's a good stock even without them.

With a few containers of this great stock in the freezer, you will be ready to make delicious soups and stews to warm your evenings in the winter months ahead.

Roasted Vegetable Stock
1 large onion
2 large carrots
1 large potato
1 large parsnip (optional)
1 stalk celery
3 garlic cloves
1 tbsp olive oil
salt and pepper
4 dried shiitake or porcini
2 bay leaves
1/2 tsp black peppercorns
1 tbsp tamari
7 cups water

Preheat oven to 450°F.

Remove the papery peel from the onion and slice it thickly. Scrub the carrots and potatoes and cut in 1" chunks. Peel the parsnip and cut in 1" chunks. Chop the celery in 1" lengths. Place the garlic cloves, unpeeled, on your cutting board and crush with the side of your big knife.

Place the above vegetables in a lightly oiled baking pan. Drizzle with the olive oil and sprinkle with salt and pepper. Roast until lightly browned, turning once, about 30 minutes total.

Meanwhile, soak the dried mushrooms in 1 cup water until softened. Remove them from the water and check for dirt or grit. Pour the soaking water through a coffee filter, straining out any grit. Reserve mushrooms and soaking water.

Put the roasted vegetables in a 4- to 6-quart slow cooker. Add mushrooms and soaking water, bay leaves, peppercorns, tamari, 1 tsp salt, and water. Cover and cook on low for 8 hours.

Let cool slightly, then strain through a fine mesh sieve into a large bowl. Press the vegetables against the side of the sieve with a wooden spoon to get the most liquid possible. Discard the vegetables. The stock will be a rich golden color. Either use it right away, refrigerate it for a few days, or freeze for longer storage.

Makes about 8 cups.
