Variety	Best for
Black Beauty	Everyday cooking, sautéing, and baking: tender dark-green flesh, the standard supermarket zucchini.
Costata Romanesco	Grilling and raw: ribbed Italian heirloom, firmer and nuttier, holds its shape.
Golden	Salads and roasting: yellow skin for colour, mild and slightly sweet.
Round (Eight Ball)	Stuffing and baking whole: spherical, scoops into a natural cup.
Cousa (Lebanese)	Middle Eastern stuffed dishes: pale, stocky, thin-skinned and mild.

Which should I pick?

For everyday cooking, sautéing, and baking, Black Beauty is the default: dark green, tender, widely stocked. No Black Beauty? Costata Romanesco has firmer, nuttier flesh that holds up grilled or shaved raw. Golden zucchini adds colour to salads and roasts, while round varieties like Eight Ball are built for stuffing.
