Jerusalem Artichoke and Potato Chips with Mustard Salt

Steak and chips is an Australian institution, and my take on this classic involves perfectly crisp Jerusalem artichokes sprinkled with a punchy mustard salt. They're the perfect partner for the robust T-bone.
The potatoes and Jerusalem artichokes can be sliced in advance and kept in separate bowls covered with water to ensure they don't brown. Just be sure to drain them well before cooking. Use a mandoline slicer or vegetable peeler to thinly slice the chips.
