What is Opo Squash?
We went to Mississauga a few days ago and I visited some food markets (Oh, how I love those!). Came across some exotic produce, like these green squash. They were labelled as 'Pakistani squash.' I hoped the owner would be able to enlighten me with more details, but no luck. So, of course I called mum who solved the mystery, "It's a type of bottle gourd," she explained.
And after some digging, I discovered they are known by several other names: calabash, and opo squash in the west and dudhi or lauki in the Indian subcontinent. It's a type of summer squash, and comes in an array of shapes and sizes. It has light green skin with an ivory white flesh, and grows in a climber plant.
I must admit, I didn’t have a lauki recipe up my sleeve when I picked up these. It was the first time I had encountered this squash and had no clue. I could make a curry but pushed myself to consider something unfamiliar. For the last few days, they've been sitting on my counter, calling me. And so, I listened today and made soup.
What if I Don't Have Lauki?
No lauki? No worries. Like lauki, other bottle gourds are versatile and delicate in flavour, and would create an equally delicious soup recipe. It's perfect for any day of the week and offers something distinct and tasty.
You all know how I love fattafat (quickly) when it comes to cooking. This spicy lauki soup can be made in less than 30 minutes. Even better, most of the cooking time is hands free - so you can enjoy your family. The minimalist use of spices creates a simple, yet delicious soup that releases just the right amount of heat from the chillies. YUM.
Health Benefits of Bottle Gourd - Lauki

The lauki squash is rich in potassium (which has shown to support blood pressure reduction), vitamin C (to boost your immunity) and vitamin A (to support eye health and immunity).
How to Peel Opo Squash
Opo squash is very easy to cut, simply use a sharp knife to cut the squash into large, manageable pieces. Cut the skin off of the squash making sure to not waste too much flesh. Then cut the peeled squash into smaller pieces ready for making your squash soup.
