Whisk the 2. 0 tbsp (40g / 1.41 oz) of tamarind concentrate with 1. 5 tbsp (22g / 0.78 oz) of water in a small bowl until smooth, then stir in the mint, cayenne, coconut, garam masala, crushed seeds, and salt to form a thick paste.
Preheat your oven to 375°F (190°C).
Peel the 8. 0 bananas and, using a sharp paring knife, cut a lengthwise slit two-thirds of the way through the flesh, leaving 0. 25 inches (6 mm) uncut at each end.
Stir together the 0. 5 cup (155g / 5.5 oz) of maple syrup, 2. 0 tbsp (30g / 1.06 oz) of crystallized ginger, lime juice, orange juice, and 2. 0 tbsp (28g / 0.99 oz) of melted butter until the glaze is well blended.
Pour the syrup mixture evenly over the bananas and bake for 20. 0 minutes, basting the fruit occasionally with the juices from the pan to ensure they remain moist and well-glazed.
While it is traditionally a side dish for a savory meal, it works beautifully as a dessert. For a more indulgent experience, serve it warm with a dollop of unsweetened Greek yogurt or a scoop of vanilla bean ice cream to contrast the heat of the ginger and cayenne.
