Broccoli varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common broccoli varieties compare.

Variety	Best for
Calabrese	Everyday roasting, steaming, and stir-fries: sturdy green florets on a thick stalk, the standard supermarket head.
Tenderstem (Broccolini)	Quick sauté and steaming: a kai-lan and broccoli hybrid with long thin stalks that cook in minutes and stay sweet.
Sprouting broccoli (purple or white)	Spring side dishes and pasta: tender slim stems and small florets, steam or quick-roast.
Romanesco	Roasting and showpiece sides: lime-green fractal florets with a mild nutty flavour that holds shape.
Chinese broccoli (Gai lan)	Wok dishes and oyster-sauce sides: leafy stems with small florets, blanch then stir-fry.

Which should I pick?

For everyday roasting, steaming, and stir-fries, Calabrese is the default supermarket pick. No Calabrese? Tenderstem (Broccolini) cooks faster with sweet, tender stems. For roasting that holds its shape with a nutty edge, choose Romanesco. For Asian stir-fries, Chinese broccoli (Gai lan) brings leafy bite to wok dishes.
