Combine bay leaves, ginger and garlic and have at the ready (they do not need to be mixed). 

Heat oil over small-to-medium frying pan or skillet over medium heat. Add Bengali Five Spice (also known as Panch Phoron), and stir until seeds begin to pop, about 30 seconds. 

Add bay leaves, ginger and garlic all at once, and stir until ginger softens, about 3 minutes. Remove skillet from heat, and stir in coriander and salt. 

Let sit until fragrant, about 30 seconds. Add yogurt and flour mixture, stir to loosed browned bits, and let marinade cool.

Combine marinade with chicken, bell peppers and carrots, stir or toss to coat, and cover (you can use a dish with a tightly fitting lid or a resealable plastic bag). Chill at least 2 hours or overnight.

Preheat oven to 475°F with rack set in upper third of oven. Arrange potatoes in single layer in large rimmed oven dish or on rimmed baking sheet. 

Turn out marinated ingredients over potatoes, mix to coat, and pat to single layer. 

Bake until browned, about 40 to 45 minutes, turning with wide spatula every 15 or 20 minutes and ending with chicken skin-side up.
