• 
• Ensure that the Fish chunks are thoroughly washed before applying a small amount of Salt and Turmeric Powder to them.
• In a large bowl (preferably a Glass Bowl with a lid), whisk the plain curd or plain yogurt using a spoon.
• Next, incorporate the Onion Paste, Ginger Paste, Garlic Paste, Bengali Garam Masala Powder, Kashmiri Chilli Powder, Turmeric Powder, Sugar, Salt, and Mustard Oil into the yogurt, ensuring they are well combined.
• To dilute the mixture, add a minimum of two cups of water.
• Place the Fish pieces onto the yogurt mixture, ensuring that each piece is evenly coated, and allow them to marinate for approximately 45 minutes to 1 Hour.

To Make Doi Maach in the Microwave

• Place the fish, along with the marinade, into a microwave-safe bowl that has a lid.
• Microwave the bowl on medium heat, or 40%, for 20 minutes.
• Following this, uncover the bowl and insert sliced green chilies.
• Proceed to microwave the bowl on high heat, or 100%, for an additional 10 minutes. This will infuse the Doi Maach with a delightful scent of green chilies while preserving their vibrant color.

Making Doi Maach in a normal Stovetop

• If a microwave oven is not accessible, simply place the fish in a pan with the curd mixture and cook over low heat for 15 minutes.
• Then, increase the flame to high and cook for an additional 5 minutes after adding green chilies.
• Allow the dish to rest for 10 minutes before serving.
