Peel and cut the bottle gourd in to smaller pieces. Coarse blend with 1 cup of milk. Here I cooked this in microwave for about 10 minutes on high to speed up the process. Then put inan electric pan to cook rest of the time.
You can cook the entire process on the stove top. I let it cook on medium high to evaporate the excess water to half which took about 45 minutes. Then add green food colorin. Her eI used natural gel food coloring about 2-3 drops.
After about more than half of water is evaporated, add 1.5 cups of sugar or sugar substitute to the sweetness level to suit your taste. Add ghee ¼ cup.
Add cardamom powder, saffron soaked in 10 ml of milk. Continue to cook; add rest of the ghee. The halva will start getting together and the ghee starts to come out. AT this stage add the fried nuts and raisins.
Take out in to serving bowls and enjoy!
