If you can find lotus root, you're in business. I managed to find some in the local Japanese grocery store (and of course, got sucked into a cartload of other items while I was there). Then, it's just a matter of slicing them thinly, frying them in some vegetable oil, and tossing them in a wonderfully fragrant spice mixture of salt, Sichuan peppercorns, dried chillies and star anise. They are very beautiful and delicate-looking and they pack quite a punch.
P.S. I'm contributing a series of photographic kitchen tours (in Manhattan) to Apartment Therapy's great kitchen-related site, "the kitchn." Check out the first one here.

Salt and pepper lotus chips (from Donna Hay Magazine, Issue 37)
2 tablespoons sea salt flakes (note: I thought perhaps they were a tad salty, consider reducing this and adding additional salt in the end to taste)
1 teaspoon Sichuan peppercorns
4 small dried chillies
3 star anise
vegetable oil for deep frying
1 kg (2 1/4 lb) fresh lotus root, peeled and thinly sliced (note: keep slices in acidulated water until frying: they turn color easily)
Place the salt, Sichuan peppercorns, dried chillies and star anise in a small frying pan over high heat. Cook, stirring for 2-3 minutes or until aromatic. Remove from the pan, place in a small food processor and process until combined. Set aside.
Heat the oil in a large deep saucepan over medium heat until hot (~350 degrees F). Deep-fry the lotus root slices in batches for 2-3 minutes or until golden and crisp and drain on absorbent paper. Place the chips in a bowl with the salt mixture and toss to coat. Serves 8.
I'm submitting my peppercorn photo to this month's "Click" event which has a theme of "metal". Feel free to jump over and vote after all the entries are received on March 30th.
