Thanks to my immigrant farmers, I can find some vegetables that are common in India, but hard to find in mainstream grocery stores here, the lauki is a good example. I bought these at the Oakland Chinatown farmers' market, they were fresh and perfect. Look for the young ones that are not too big.
I like to cook lauki from time to time to introduce some seasonal variety to my cooking. I peel it and then cut it in to small pieces.
Saute one medium sized onion, garlic, and whole dried red chili peppers, add some cumin as well. Add three medium sized tomatoes and saute until the oil separates, add cumin, and turmeric, and the pieces of lauki. Add about two cups of water, and cook at medium heat for 15 minutes, lower the heat and cook for another 10 minutes or so, until the lauki is fully cooked.
