North India grows lovely sweet potatoes, they are white-fleshed, sweet and creamy. When in season, they are grilled whole in their skins on street stalls and served with lemon juice and the delicious spice blend chaat masala, that balances out their inherent sweetness. This is a Westernized, embellished version of that dish, made with orange-fleshed sweet potatoes. It works really, really well. It is a fusion dish but one that, for me, works better than both originals and makes an amazing summery salad.
