Jerusalem Artichoke Soup
October 29th, 2011 by Dawn Becker
The weather has turned quite brisk and with the seasons’ harvest of root vegetables, I’ve had soup on the brain. I picked up a handful of Jerusalem artichokes earlier this week and decided to treat myself to a velvety bowl of soup for lunch. Jerusalem artichokes are nothing like the prickly globe artichokes. These are tubers from a type of sunflower, are closer in taste and texture to potatoes and have the appearance of knobby ginger root.
Vegetable puree soups are one of the easiest things to make. Most recipes follow a similar cooking method which is to sautee some aromatics in a pot, usually diced onions, until translucent. Then add whatever vegetable you’re using that’s been cut up into small uniform pieces (so they cook evenly) such as carrots, butternut squash, potatoes, broccoli and cauliflower, and sautee for a few minutes. (TIP: The smaller you dice your vegetables the less time they have to simmer.)
Then add some herbs, spices or other flavourings like ginger or cinnamon. Pour in some chicken (or vegetable) stock just to cover the sauteed vegetables. Bring to a boil and then turn the heat down to simmer until the vegetables are soft. I then puree the whole mixture in a blender or with a hand blender directly into the pot, which is so much easier for clean up. I then add seasonings, salt and pepper to taste and an optional addition of heavy cream depending on your preference. Cream is not necessary but it adds a lusciousness to some types of soups. Too much cream and your soup will be ruined because pureed soups have such a delicate vegetable flavour.
I like to add a flourish with some toppings to finish off my soup. Here you can get a little creative. For the Jerusalem artichoke soup, I like to top it with some prosciutto crisps and a sprinkling of chives. Beet soups or cabbage soup call for a dollop of sour cream that gives it an Eastern European flair. Broccoli or cauliflower soup work really well with a dash of hot pepper sauce and some grated sharp cheddar. Be creative and have fun with your soup. It’s a great way to enjoy your vegetables on a bitter cold day and here in Toronto, we’re sure to have many more chilly nights ahead.
Jerusalem Artichoke Soup
1 lb of Jerusalem artichokes
1 small potato
1 onion
1 Tbsp olive oil
1 bay leaf
2 cups of chicken stock
3 Tbsp heavy cream
salt and pepper
Peel and dice the Jerusalem artichokes and potato. Have a bowl of cold water handy with a squeeze of lemon juice in it and drop the diced artichokes and potatoes into the bowl to prevent discolouration. Dice the onion. In a large pot, heat the olive oil over medium high and sautee the onions about 5 minutes until translucent. Be careful not to brown the onions.
Drain the artichokes and potatoes and add them to the pot with the onions. Add the bay leaf. Sautee for 2 minutes. Add the stock. The stock should just cover the vegetables. If not, add more stock or some water to cover. Bring to a boil then lower to simmer for 20 minutes until the vegetables are soft.
When the vegetables are ready, remove the pot from the stove. Remove the bay leaf and using an immersion hand blender, whizz the vegetables right in the pot until smooth. Season to taste with salt and pepper.
You may wish to blend in a few tablespoons of heavy cream. I use no more than 3 tablespoons for this soup as Jerusalem artichokes have a delicate flavour and the taste can be easily overwhelmed by the cream. You can also skip the cream altogether to keep this vegetarian (of course using vegetable stock instead of chicken stock). Serve topped with prosciutto crisps and some chive snippings.
Prosciutto Crisps
Super easy to make. I use one slice of prosciutto per serving. Heat a few droplets of olive oil in a pan on medium high just to lightly coat the pan. Add the prosciutto slices and cook until brown a minute or two and then flip to brown the other side. Remove from heat and place on a paper towel lined plate to soak up excess oil. The prosciutto will crisp up as it cools. You can then crumble it with your fingers and use as a topping for soups or salads. If you prefer uniformly sliced prosciutto crisps just cut them into slices of your desired thickness before you drop them into your hot pan. Alternatively you can also broil prosciutto slices on a cookie sheet in an oven, if you prefer not to fry them, but I personally can’t justify heating up my whole oven to make prosciutto crisps in order to avoid a few drops of oil.
