Vietnamese grilled eggplant with scallion oil

Smoky eggplant, bright balance

Cà tím nướng mỡ hành is a Vietnamese preparation that pairs grilled eggplant with mỡ hành: scallions in hot oil. The name describes the main ingredients, not one set presentation. The eggplant can be roasted whole and then opened up, so the tender flesh holds the oil well. Here, it’s served with a light fish sauce and lime dressing. That adds salt, acidity and a little sweetness to balance the smoky, mild vegetable.

Grilling whole eggplants works well because the skin protects the flesh as it softens inside. Under a hot oven broiler, the outside chars; on a barbecue, the vegetable picks up extra smoky flavor. Turn the eggplants regularly and wait until they have collapsed and softened all over. The time needed depends on their size and the heat. Before grilling, prick the skin in a few places with a fork to let the steam escape. Let them cool briefly after grilling before cutting them open.

Scallion oil is simple, but the temperature matters. Pour the hot oil over finely sliced scallions: they wilt right away and release their fragrance without needing to cook for long or turn brown. Use a neutral oil, such as sunflower oil, so it doesn’t overpower the scallions and eggplant. Fish sauce, lime juice, water and sugar come together to make a thin dressing. Stir until the sugar dissolves, then taste; fish sauce varies in saltiness by brand, so keep the dressing on the side and let everyone add it to taste.

Choose eggplants that feel firm and aren’t too large; smaller ones often cook more evenly. Lime can be replaced with lemon if that’s easier to find, though lime has a different aroma. No fish sauce on hand? Soy sauce can be used as an alternative, but it gives a different flavor and makes this a variation. The roasted peanuts are optional: they add a distinct crunch alongside the tender flesh. Leave them out for a smoother result.

Serve the eggplants warm or at room temperature as a starter, with the dressing in a bowl on the side. They also go well with rice and other Vietnamese dishes, for example as part of a meal served with several dishes. It’s best to prepare the eggplant shortly before serving; leftovers can be covered and kept in the refrigerator for up to two days. Reheat them gently or serve them cold, and add the scallion oil and dressing just before eating.
