What to Look Out For
- Clear kosher certification from a recognised authority (e.g. OU, OK, Star-K)
- Simple, transparent ingredient lists with no hidden additives
- Trusted brands or kosher authority guidance, where some products may be approved even without a visible symbol
What to Avoid
- Products with vague labelling, making it difficult to verify ingredients and processing
- Assuming all fruit juice is automatically kosher, particularly for grape juice which has stricter requirements
- Items that look kosher but are not certified for Passover when required
