Adapt it for your goals.
Low-oil
Reduce coconut oil to 1 tbsp total and use a non-stick pan. Sauté aromatics in a splash of water instead of oil for a lighter version without sacrificing the roast character.
high proteinHigh-protein
Swap mussels for an equal weight of skinless chicken thigh pieces, cut small. Increase cooking time to 15-20 minutes until chicken is cooked through and the masala is dry.
jainJain
Replace mussels with 200g of paneer cubes or 1 cup of chopped mixed vegetables (carrots, beans, peas). Omit garlic and onion, use asafoetida (hing) for the onion-like flavor. Cook until vegetables are tender and masala is dry.
veganVegan
Substitute mussels with 200g of firm tofu, pan-fried until golden, or 1 cup of button mushrooms, halved. Use the same spice mix and cooking method for a plant-based version that mimics the meaty texture.
