Anyway, ash gourds are not available north of London, as far as I’m concerned and even then, I think, available only at South Indian or Sri Lankan greengrocers. Since I live in the Midlands (which is not really far north, but is northern enough for Londoners, I’m sure), I can go for years (and have done) without ever laying eyes on an ash gourd.
My most favourite thing to make with ash gourds is kootu, cooked with chana dal – an incredibly simple preparation.

The most work involved is in prepping the vegetable for cooking, by removing the somewhat jelly-like mid-section which contains the seeds and chopping the firm flesh of the gourd into small cubes.

After that, it’s easy peasy. This kootu is versatile (in my house anyway) as a side-dish with sambar and rice, or with chapaties, or over plain rice as a simple meal.
Recipe for: Pooshanikkai (ash gourd) kootu

Ingredients:
2 cups ash gourd, cut into small cubes
1/2 cup chana dal
1/2 tsp turmeric powder
3 tbsp fresh grated coconut
3-4 green chillies
1/2 tsp cumin seeds
1 tbsp rice flour
1 tsp mustard seeds
2 tsp urad dal
5-6 fresh curry leaves
1 tsp oil
1/4 tsp asafetida powder
Salt to taste
Method:
1. Put the chana dal at the bottom of a pressure-cooker-safe vessel, add the cut ash gourd pieces and the turmeric powder, and 3/4 cup water.

2. Pressure-cook this for 3 whistles, let the pressure reduce naturally. The ash gourd pieces will be translucent when the cooker is opened.

3. Grind the coconut, green chillies, rice flour and cumin seeds to a smooth paste using 3-4 tbsp hot water.

4. In a pan, heat the oil and add the mustard seeds, asafoetida powder, urad dal and curry leaves and let them fry till the seeds pop and the dal is golden brown (30-40 seconds).

5. Carefully pour the cooked pumpkin/gourd along with the cooking water into the pan and stir well.

6. Now add the ground coconut paste and stir it in along with salt to taste. Add a little more water if required (depending on the consistency you want for the kootu.)

Bring the kootu to a gentle boil and simmer for 2-3 minutes. Serve hot.
