Longor

What Mr Fothergill's says

A long banana shallot with a robust flavour for salads and casseroles. Copper-coloured skins; each set produces a cluster of up to nine bulbs that store well. Sweeter and more delicate than onions, milder than garlic; cook, pickle or eat raw. Easy to grow in little space for a summer harvest. 500g pack, approx. 30 shallots.
