Roughly chop ash melon/gourd, ginger, tomato, chilies, and cilantro. Set aside.
Use a medium sized pan on the stove on medium heat
Add 1 tbsp olive oil
Add ash melon/gourd, tomato, ginger, chilies, cilantro and tamarind to pan and cook until vegetables turn soft.
Add turmeric powder, asafoetida powder, monk fruit sweetener and salt to the vegetables on the pan. Cook for few minutes. Make sure all vegetables are soft.
Turn off stove. Let the mixture cool for 5 minutes. Then transfer to a blender. Blend until a creamy consistency.
Turn the stove back on medium heat using the same pan. Add 1 tsp olive oil. Then add mustard seeds and curry leaves. Cook until mustard seeds start crackling. Be careful when the mustard seeds start crackling as they tend to fly out in different directions. Use a cover if available.
Turn off stove, spoon out the mustard seeds and curry leaves to the creamy chutney mix.
Enjoy this chutney with keto dosa or keto naan
