Cucurbita pepo var. torticollia
Gourd or Pumpkin Family-Cucurbitaceae
Also known as Crookneck.
The yellow crookneck squash is a summer squash. It has a wide bulbous blossom end that tapers to a long curved, narrow stem end, referred to as the neck. It has a thin pale yellow skin with a slightly pebbled (bumpy) texture. The skin can also be smooth. The flesh is yellow and sweet.

How to Cook yellow crookneck
yellow squash and zucchini are cultivars of the same species, Cucurbita pepo. So cook it the way you would a zuchini.
Since it’s a summer squash, it has over 90% water, immature seeds and a thin skin. All parts including the skin is edible.
It can be roasted, baked, steamed, sautéed, stir-fried or braised. Take care not to overcook it. It should remain a little crunchy.

One of my favorites. I hope my plants will soon take off, so far they are hesitating, not hot enough I guess.
My favorite way to prepare them is to slice and lightly cook in a bit of butter or olive oil, maybe some garlic.
They get bumpy with age so it’s better to pick them before that.
I fried them in a little butter the other day and served as a side with some rice. They were delicious!!!

This looks so much like the bitter gourd, but on the inside is softer I guess
Yes, of course!
