Lady Godiva - the flesh is flavored much like a spaghetti squash, though the strands aren't as large. The interesting thing with this squash is that the seeds do not have a seed coat, they are naked, so you have instant pepitas, no work cracking them out of the shell! Just season, roast and meat.
Red kuri is a Japanese variety that is similar in flavor to a pie pumpkin
Boston marrow is a very large, sweet winter squash. Roast on low heat in the oven to soften the peel for easier removal, then crack it open and cook. Cube out the parts you are not ready to eat and put them in the freezer for later!
