MB 321.3 – MB 321.4 – Salting Foods on Shabbos: When It Becomes “Like Cooking”

Salting certain foods on Shabbos can resemble pickling, which Chazal prohibit because it is considered similar to cooking. The restriction primarily applies when salting multiple pieces (e.g., radishes, onions, garlic, cucumbers) together, as this appears like a preserving process.

However, salting or dipping individual pieces and eating them immediately is permitted, provided they are not left long enough to release significant moisture. Practices that involve leaving salted vegetables to sit (even briefly in a way that mimics pickling or tanning) are prohibited. Adding oil or vinegar right away may mitigate concerns, depending on the method.

Foods not typically preserved through salting (e.g., eggs) may be salted without concern. The accepted practice is to avoid salting in a way that resembles pickling and instead salt each piece individually and consume it promptly.
