Britannia 50-50 Maska Chaska is a popular Indian buttery, salted cracker featuring a distinct "maska" (butter) and "chaska" (spicy/tangy) flavour profile. These square-shaped crackers are topped with aromatic spices and herbs (like chives), offering a crunchy, light texture often paired with tea, coffee, or soups. [1, 2, 3, 4, 5]
