Variety	Best for
Butternut (standard)	Everyday roasting, soup, and curry: sweet orange flesh that purées smoothly, the all-purpose supermarket squash.
Waltham	Pies and roasts where flavour matters: heirloom benchmark with deep, sweet, nutty flesh.
Honeynut	Single servings and roasting whole: palm-sized mini version with very sweet, concentrated flesh.
Crown Prince	Roasting and gnocchi: blue-grey skin and denser, drier flesh that holds its shape and substitutes well for butternut.

Which should I pick?
