is the classic Indian version of Italian biscotti and is made the same way. Regal Original Cake Rusk is manufactured using the finest ingredients to ensure you can enjoy its classic taste during memorable moments. A rusk is a hard, dry biscuit or a twice-baked bread. It is sometimes used as a teether for babies. In some cultures, rusk is made of cake, rather than bread: this is sometimes referred to as cake rusk. Since rusks are dry and hard biscuits, they are best dunked in some liquid, like milk, coffee or my favorite thing to pair them with is chai. It becomes soft and just melts in your mouth.
