Dudhi Koshimbir / Dudhi Raita

One of my fav. Raitas, a lot healthy and quite coolant for your tummy. Do include it in your diet once in fortnight.
I have not given Ingredients in gms or Tsp or anything. You can adapt it depending on how much you have to prepare.

Ingredients: 
Dudhi / Bottle gourd , peeled off and chopped into small cubes.
Yogurt
Cumin powder
Salt
Dried Mint leaves powder
Mustard powder ( Take 1 spoon of mustard seeds and grind in mortar and pestle
Sugar
For Tadaka,   oil, cumin seeds,green chili, curry leaves
for garnishing fresh mint leaves, coriander leaves finely chopped.

Procedure:

1. I took a medium sized Dudhi for raita. Peel of the Dudhi and cut into cubes. In a pressure cooker, put all the cubes in a container without putting water. just pour 2-3 spoons of water. or just sprinkle water. Pressure cook for couple of whistles or 3 whistles ( depending on the pressure cooker you have). Cook until they are soft but shouldn't be overcooked otherwise while mixing the yogurt and other ingredients it will become paste.  
2. Drain out the water if any in the container and keep the boiled cubes to cool down completely. I would suggest, keep them aside and carry on with your rest of the cooking.
3. Once cooled down properly, take enough Yogurt in another container and whisk it to have an even consistency in the yogurt and it doesn't leave water when poured into Dudhi. Quantity of Yogurt should be as much to cover whole quantity of Dudhi you have taken. Take little quantity at a time and add in if needed.
4. Pour the whisked yogurt into cubes, add little bit sugar ( to balance the taste), cumin powder,dry mint powder, mustard powder and mix well gently. 
5. Prepare Tadaka in different pan. First oil, once heated add cumin seeds, curry leaves,green chili/s. Pour this on Raita. Give a mix.
6. Garnish with couple of mint leaves and chopped coriander leaves.
7. Just Before you serve, add salt to taste and mix. If you put salt at the preparation time, it will leave water until you serve.

Health benefits of Dudhi / Bottle Gourd :

The cooked vegetable is cooling. It gives a feeling of relaxation after eating it.

Bottle gourd is very valuable in urinary disorders. 

The juice of bottle gourd is a valuable medicine for excessive thirst due to severe diarrhoea, diabetes and excessive use of fatty or fried foods.

Its use during summer prevents excessive loss of sodium, quenches thirst and helps in preventing fatigue.

The juice of the fruit is used in the treatment of stomach acidity, indigestion and ulcers.

Bottle Gourd helps in constipation. Bottle gourd is not only rich in essential minerals, iron, protein and trace elements; it is also rich in Fibre. Fibre is known to be missing in the modern diet, the absence of which is the cause of not only constipation but other digestive disorders like flatulence and even piles. Hence diet using different preparations made from this vegetable are useful.
