I tried making bread from scratch

The humor in this joke rises from a delightful bit of wordplay, specifically a pun that plays on similar-sounding words. The setup, about making bread from scratch, immediately brings to mind the physical act of "kneading" dough – an essential, hands-on part of the baking process. The punchline then cleverly swaps "need" for "knead" in the common idiom "need-to-know basis." The unexpected collision of a kitchen activity with a phrase usually associated with secrecy or restricted information is what makes the joke funny, creating a silly image of bread-making as a highly classified operation.

Making bread from scratch has been a popular pastime for centuries, experiencing a recent resurgence as people embrace home baking for its therapeutic qualities and delicious results. It's a process that genuinely does require a certain amount of hands-on knowledge, or "knead," to get it right. The phrase "need-to-know basis" itself has a long history, often used in military, government, or corporate settings to describe information protocols. Applying this formal, almost clandestine phrase to the humble act of baking bread creates a charmingly absurd contrast (Review), implying that perhaps some baking secrets are best kept under wraps!
