Opo Squash is actually not a squash, but a gourd. Its many names include "Long Squash" (particularly in Canada), and "Snake Gourd". It is narrow, and anywhere from 15 to 90 cm (6 to 36 inches) long, and 7 1/2 to 30 cm (3 to 12 inches) wide. It can curve in on itself, or be stout and plump.
The skin can be yellow to green. It has a hard skin, that stays tough after cooking. Inside, it has white, firm flesh with seeds in it. It will have a mild taste when young, getting bitter as it ages. Its subtle taste, like zucchini, needs something with it to make it interesting. Choose firm ones, with no blemishes and the stem still attached. Younger, smaller ones are sweeter and more tasty.
