Our first dish is this light, creamy sunchoke soup, dressed up with a vibrant pomegranate reduction. Yerba mate was used to infuse this soup, as one of the most celebrated flavours of Argentina. I've always loved the energizing taste of mate tea, together with the fact that it contains no regular caffeine.
2 lbs Jerusalem artichoke/sunchoke
1 leek (white part only, if you want to keep the soup white in colour) - chopped
3 cloves garlic - chopped
juice of 1 lemon
2 sprigs fresh rosemary
salt and pepper - to taste
6 cups steeped Yerba mate tea
2 large pomegranates
Scrape the sunchokes with a sharp knife to remove the brown skin. (I've tried a variety of techniques, such as blanching the roots in order to make the process of removing the skin easier, but scraping is the only one that worked for me.) If you're not particular about the colour of your soup, I've read that it is not necessary to peel them completely, or at all. Make sure to put the peeled sunchokes into a bowl of cold water with some lemon juice, to prevent discoloration. Chop the sunchokes into one-inch sized pieces. Gently heat olive oil in a medium sized pot, add sunchokes, leek and garlic, and saute for a couple of minutes. Add lemon juice, rosemary sprigs, salt, pepper, and about two thirds of Yerba mate. Bring to a boil, turn the heat down, and let simmer for about 30 minutes. Remove rosemary sprigs (if the colour of the soup is important). In a blender, blend the soup until smooth. If the soup appears too thick, add more of the mate and bring to a gentle boil, then remove from heat. Adjust salt and pepper. Serve with pomegranate reduction.
Score the skin of a pomegranate to make 8 parts. Fill a large bowl with water, and break the fruit into 8 pieces, holding it under water (that way you won't get pom juice all over yourself). Separate the kernels from the skin and white parts under water. The kernels should fall on the bottom of the bowl, while the rest will rise on the surface. Discard the skin and white parts, and drain the kernels using a colander. In a high speed blender, carefully pulse the kernels, releasing the flesh and juice, but not breaking down the seeds. Strain through a fine strainer and discard the seeds.
Pour the juice into a shallow dish and place it in the dehydrator at 115F for several hours, until the liquid is reduced to a thicker consistency. Store in a covered container in the refrigerator. The reduction can also be done the conventional way, using the stove.
