Good timing starts with good sources.
Cooking charts establish reference cases. Government food-safety guidance establishes the final check. Each guide lists its specific sources.
How to read a source
A linked chart supports the stated reference shape and range. Adjustments and category transfers are identified on the guide and explained in our methodology. Retrieval dates describe when the reference was checked; they are not a claim that every food was tested in our kitchen.
