A Bengali parcel of tender banana blossoms and diced wax gourd smothered in a pungent mustard paste, wrapped in banana leaves and chargrilled until smoky.
Soften 1 banana leaf over gentle heat, then cut it into 10 pieces roughly the size of your griddle or tawa.
Strip the outer bracts from 250 g banana flowers to collect the florets. Discard the stiff central stamens and tough base calyxes from each blossom, finely chop the petals, and submerge them in water for at least 1 hour or overnight. Drain thoroughly and squeeze out all excess moisture.
In a blender or mortar, grind 125 g mustard seeds, 12 g green chilli, 4.2 g granulated sugar, 114 g mustard oil, 2 tablespoons of water, and salt to taste into a uniform paste.
Place the squeezed banana flowers into a large bowl along with 200 g wax gourd, 125 g onion, 36 g green chilli, the mustard paste, salt to taste, and the ground spices. Mix until the vegetables are evenly coated.
Brush the griddle or tawa with a little extra mustard oil and lay down 5 banana leaf pieces. Spoon the vegetable mixture into the middle, cover with the remaining 5 leaf pieces, tuck the edges beneath the filling, then fold up the bottom leaves and tie them over the top into a secure parcel.
Set the griddle over high heat and chargrill until each outer leaf layer burns away, leaving only the innermost leaf. Carefully flip the parcel over and repeat on the other side. Unwrap the parcel to serve.
Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.
Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.
Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.
Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.
