How to cook: Ovo-vegetarian fingerling sweet potatoes with aioli

Place the unpeeled sweet potatoes in a pot, cover with water and add salt. Bring to the boil, lower the heat and simmer for ten to twelve minutes.

Why not peel them first? I tried that — the sweet potatoes fell apart during cooking. The skin keeps the flesh intact and the starch contained.

Cool the sweet potatoes. Using a small knife, scrape off the skins. Cut each sweet potato in half lengthwise.

Arrange the sweet potatoes, cut side up, on a plate. Sprinkle with salt, pepper and scallions. Serve at room temperature with aioli.
