Bright with blemish-free skin and firm to the touch, these fresh onions have the distinctive savoury flavour that only onions bring to a dish. Ideal as the base for all your favourite dishes, but also great quartered, drizzled in olive oil and roasted. Serving Suggestion To add flavour to roast vegetables, peel an onion and thickly slice.
