Product Overview
Kabocha squash, commonly known as Japanese pumpkin, is a winter squash widely traded in fresh produce markets. It is valued for its sweet flavor, dense texture, and versatility in cooking. Kabocha is an important commodity in both retail and food service sectors, particularly in Asian and fusion cuisines.
Key Characteristics
Kabocha squash is round to slightly flattened with a hard, dark green rind that may have lighter green stripes or patches. The flesh is deep yellow to orange, dense, and becomes smooth and fluffy when cooked. Flavor is sweet and rich, often compared to a combination of pumpkin and sweet potato. The skin is edible when cooked. Kabocha is non-climacteric and does not ripen further after harvest.
