Squash figures in a ton of Southeast Asian dishes. In the Philippines, we call squash kalabasa.
Uncut, kalabasa is round (occasionally, the top and bottom may be flattened), the thick hard skin is green (sometimes grayish) with specks of yellow and yellow green. Inside, the flesh is yellow-orange. The flesh cradles the hollow core where the seeds are loosely stored.
Visually, the inside of the kalabasa is like pumpkin. To the untrained eye, if kalabasa and a pumpkin that had been cut open were placed side by side, it might be difficult to guess which is which without peeking at the color of the skin.
What we call kalabasa (calabaza in tropical America) is not a pumpkin but common usage can be a source of confusion. So, let’s decipher this kalabasa-pumpkin issue. Let’s start with the plant family Cucurbitaceae. It’s a huge family that includes gourds, melons, cucumber and even loofah. The Cucurbitaceae family is divided into some 95 genera, one of which is Cucurbita.
What we call kalabasa in the Philippines can be Cucurbita moschata or Cucurbita maxima. Originally from tropical America (where it is called calabaza) where many regions were also Spanish colonies, it is reasonable to assume that it was the Spaniards that introduced calabaza to the country.
Pumpkin, on the other hand, is Cucurbita pepo. Pumpkin is round and the color varies from deep yellow to bright orange.
Okay, that’s all very interesting but what practical use is there for all that information? Well, it’s useful when substituting ingredients.
When adapting non-Asian recipes that include pumpkin among the ingredients, I substitute kalabasa. It’s sweeter, creamier and less watery. Plus, pumpkin sold in the Philippines are imported and they are pricey.
On the flipside, when non-Asian readers see a recipe with kalabasa, they ask what they can substitute for kalabasa which does not grow in cold regions. I tell them, “Use butternut squash.” It seems to be the closest in terms of texture.
So, you see, there is no such thing as useless information.
