From its vibrant hues to its versatility in global cuisines, kabocha is a culinary gem. This guide explores every facet of kabocha squash, from cultivation to kitchen creativity.
What is Kabocha Squash?
- Origin: Native to the Americas, kabocha (Cucurbita maxima) was introduced to Japan in the 16th century, where it became a staple.
- Appearance: Round, squat shape with a knobbly, dark green rind (often striped) and bright orange flesh. Some varieties have orange-red or gray-blue skin.
- Flavor: Sweeter and denser than butternut squash, with notes of chestnut and sweet potato.
- Texture: Creamy and starchy when cooked; the skin becomes tender and edible.
Global Varieties
- Miyako: Classic Japanese variety with deep green skin and rich flavor.
- Ebisu: Sweeter, with reddish-orange skin.
- Buttercup Squash: A close relative popular in North America, slightly less sweet.
- Thai Kabocha: Smaller, with a stronger sweetness and vibrant orange flesh.
