Frutin’s Mustard Kasundi is a Bengali version of mustard sauce. It is a pungent paste of fermented mustard seeds, and spices, popular as a dipping sauce in Bengali cuisine.

It is commonly served with snacks like cutlets and chops, and deep-fried spicy treats, as it brings tartness and pungency to the flavours.

It also can be served as a dip with other snacks, as well as sandwiches, pizzas, burgers, omelettes, salads and other food.
