So, I tried to explain why I haven't included too many soups, that so much of soup making is just a matter of starting with some basics and then continuing to add this and that until the flavor is what you want.
But then I was reminded that The New York Times has recently been emphasizing this kind of approach with their Wednesday Cooking email newsletter, featuring no-recipe meals for the middle of the week. Somewhat coincidentally, the Times also included an article this weekend on the variability of measuring standards over time, "A Measured Approach to Cooking."
Maybe it is time to post a basic "recipe." Potato soup is a great meal to fall back on when the wind is blowing the thermometer down to below zero windchills, so I decided to play test kitchen. I began carefully measuring as I cooked up yet another batch. The result of all that measuring is the recipe below, but you will see lots of notes and variations at the end. What I have attempted to do is provide a guide, a starting point, for soup that will match your own preferences and pantry supplies.
You will note that this makes a large amount of soup, one you may think is totally improbable for you and yours to finish before tiring of it. While that could be true, you may be surprised to discover just how many times everyone will go back to the stove to refill their soup mugs or bowls, and a container of the leftover soup will keep in the refrigerator for almost a week, ready for grabbing a serving to heat in the microwave for a fast late dinner, even midnight snack, or for packing to take to the office for lunch. If, however, you don't have pans big enough or if you are sure you want to make less, the recipe is easily halved.
One last note: While I don't generally worry about keeeping my cooking gluten free, this recipe, and most of the variations, will work for those who definitely need to stay away from gluten. The potatoes provide all the thickening needed to make really creamy soups.
Creamy Potato Soup
(For the various vegetables, I have included several different measures to help you have a guide to amounts. However, feel free to adjust as you like.)
1/4 to 1/3 c canola oil
1 large or 2 medium onions, coarsely chopped (13 oz. or about 2 1/2 c)
4 stalks celery, diced (8 oz or about 1 1/4 c)
3 lb potatoes, cut into about 1 inch cubes (approximately 8 c)--I had a mixture of white, red, and russet potatoes for this batch
1/4 c chicken or vegetable bouillon powder OR 4 to 5 bouillon cubes
approximately 2 1/2 quarts water
12 to 16 oz pureed butternut squash (about 1 1/2 to 2 c)--if frozen, no need to thaw
3 oz chopped fresh spinach (app 2 c after chopping)
3 to 4 cloves garlic, minced (I used bottled minced garlic today)
1 t dried basil
1 t dried oregano
1 t black pepper
1 12 oz can evaporated milk, either fat free or "regular"
1 to 1 1/2 c nonfat dried milk powder
4 oz processed cheese (like Velveeta in the rectangular yellow box)
1. Pour enough canola oil into a large pot to just cover the bottom of the pan. Add the onions and celery and saute over medium high heat until the onions just start browning and the celery is slightly tender.
2. Meanwhile, scrub the potatoes, cut out any spots and eyes, but do not peel. Dice into approximately one to two inch cubes. Add to the onions along with about 2 quarts of water and bouillon powder. Cover the pan and allow to simmer for about 20 minutes, until the potatoes are very soft.
3. If desired, use a potato masher to break up most of the chunks of potato. (An immersion blender can also be used for this.) Be sure to do this before adding the spinach, to avoid ending up with a kind of murky green colored soup!
4. Stir in the squash, spinach, and garlic, along with the basil, oregano, and pepper. Continue to simmer for another 5 to 10 minutes (or until the squash is completely thawed if it is put in frozen).
5. Mix the dry milk powder with a cup or so of water and add it, along with the evaporated milk, to the soup. Stir well. Cut the cheese into a couple of pieces and add. Stir until the cheese is melted and the entire mixture has returned to a slow simmer.
6. Taste for seasoning and then serve or allow to simmer together for another 10 to 15 minutes. This is also very good the second day as well.
bacon bits, either imitation or real
grated Cheddar cheese
choped parsley or cilantro
diced red or sweet onion
Yield: Approximately 1 gallon soup, enough for 12 to 16 servings.
Replace 1 quarts chicken or vegetable stock for the water and bouillon.
Omit the dry milk powder and use milk (skim, 2%, or whole) for part or all of the water.
Substitute carrot puree for the squash OR saute about 2 to 3 c sliced carrots with the onions and celery.
Omit the processed cheese. Just before serving, mix in 2 c coarsely grated Cheddar cheese and stir vigorously to incorporate it throughout the soup.
Corn chowder: Add 16 to 24 oz corn--either frozen or canned--to the mixture, adjusting the seasonings to taste. (Be aware that canned corn will add a lot of salt unless you use the unsalted variety.)
Mexican style chowder: Substitute cumin for the basil. Add corn as for the corn chowder and stir in a 4 oz can of diced green chilies and/or about half a cup of finely chopped bell peppers. For added heat, use serranos or jalapenos instead of bell peppers. Serve with chopped cilantro and grated white Mexican cheese.
Clam chowder: Omit the bouillon and use seafood stock or clam juice for part or all of the water. Stir in 16 oz canned clams, with their juices.
Vegetable soups of many kinds: Use the potato soup as a base, adding broccoli, cauliflower, or mixed vegetables in place of, or with, the spinach and squash. Finely shredded cabbage (about 2 to 3 cups) can be sauteed with the onions and celery for a surprisingly sweet addition to the soup.
Ham bone and potato soup: Omit the bouillon (to avoid an overly salty soup). If a ham bone is available, add it to the onions and celery and with 2 quarts of water and simmer for about 30 to 40 minutes, until any meat on the bone begins to come off it easily. Add the potatoes and proceed as in step 2. After the potatoes are softened, but before mashing, remove the ham bone, cut the meat off the bone and return the meat to the soup. Proceed with step 3.
Ham or hot dog soup: Cut the bouillon amount in half (to avoid having an overly salty soup). Cube some ham (2 cups or as desired) or slice a 12 to 16 oz package of hot dogs and stir in with the spinach and squash.
