Also known as Chinese icicle radish or daikon, it is long and white and rather like a carrot in shape but usually much larger. It is a winter radish or root and can withstand long cooking without disintegrating. It thus absorbs the flavours of other foods while retaining its distinctive radish taste and texture. Look for firm, heavy, solid, unblemished ones. They should be slightly translucent inside, solid and not fibrous. Always peel before use. Store mooli in a plastic bag in the vegetable crisper of your fridge where they will keep for over a week.
