What the Research Says

Ask “why?” and “how?” about H&C facts. Instead of memorising “the danger zone is 5–63°C,” ask: “Why is this temperature range dangerous?” and “How do chefs prevent food staying in it?” Dunlosky et al. (2013) rated this moderate-to-high utility.

Step-by-Step Method

1. 1
   Read a key fact — E.g. “Protein is needed for growth and repair.”
2. 2
   Ask WHY — Why does the body need protein for growth?
3. 3
   Ask HOW — How does a chef ensure sufficient protein in a menu?
4. 4
   Write answer — Without notes, then check.
5. 5
   Connect — Link protein to other nutrients, dietary needs, menu planning.
