Cooking Information

Enjoy Zuccuri simmered, sautéed, dipped in tempura batter and fried, or roasted for a saccharine, melt-in-your-mouth sensory experience. This sweet kabocha squash pairs well with warming spices like nutmeg, clove and sage, as well as pears, cilantro, spinach, and parsley.

Zuccuri holds its form well when cooked and can be added in cubes to soups, stews, curries and casseroles. For a very simple and fast preparation, try microwaving one-fourth of the Zuccuri (500g approx.) for six minutes.
