Kalabasa (Cucurbita maxima), a squash with orange flesh, is popular in Filipino cuisine; it is a species of the cucurbita family of squashes that includes pumpkins that are familiar to growers in temperate climates. Cucurbita squashes all have orange, yellow or green exteriors with creases running from bottom to top. Filipinos sometimes refer to kalabasas as pumpkins; kalabasa seeds are popular snacks in the Philippines.
Calculating Nutritional Value
The seeds of Cucurbita maxima and closely related species C. moschata, C. mixta, and C. pepto are of different sizes, but they are nutritionally identical. C. mixta and C. pepto refer to varieties of pumpkin associated with Halloween in North America. Kalabasa squash are smaller than pumpkins, and the exterior is green, but the orange flesh inside looks and tastes the same as pumpkin, and the large, flat seeds are equally flavorful. The nutritional values for curbita seeds calculated by the United States Department of Agriculture (USDA) listed here by volume are posted on Nutritionalvalues.com.
