1. Define the use case
We begin with the food, storage space, reheating route and recurring workflow. Products are evaluated as possible tools for that job, not as isolated objects competing on popularity.
2. Prefer primary evidence
Material, capacity, temperature, freezer, microwave, oven, dishwasher, warranty and care claims are checked against manufacturer pages wherever accessible. Food-safety guidance comes from authoritative public sources such as FoodSafety.gov and USDA.
3. Check the current commercial listing
Before linking to Amazon, we confirm that the product page is live and record the ASIN. We do not publish volatile prices. Availability, variants and seller details can change, so readers should check the live listing.
4. Separate research from testing
“Research-led” means we compared documented specifications and use-case fit. “Hands-on tested” appears only when a documented physical evaluation has occurred. Current product guides are research-led and not hands-on tested.
5. State limits and cautions
Product ranges may include multiple capacities and piece counts. When an Amazon set does not exactly match a manufacturer reference set, we say so and direct the reader to verify the exact live variant.
6. Review when the evidence changes
Guides display an update date. Material changes to specifications, product status or authoritative guidance trigger a fresh review of the affected advice and links. Readers can report a factual error, broken link or changed product detail through the Contact page.
