How can I efficiently break chocolate into smaller pieces for baking or snacking?

To efficiently break chocolate into smaller pieces for baking or snacking, you can use a sharp knife to carefully chop the chocolate into chunks or use a kitchen mallet to gently tap the chocolate while it is wrapped in a towel to prevent it from shattering. Another method is to place the chocolate in a resealable plastic bag and use a rolling pin to crush it into smaller pieces.
