In-depth guides, comparisons and kitchen stories — not recipes, but the things that make a recipe work.
Milk boils over suddenly because **a skin of protein and fat** forms on the surface and traps the steam beneath it, so pressure builds until it lifts the whole skin at once. The fix: **constant stirring**, medium heat…

Chocolate turns white for two different reasons: **fat bloom**, when the cocoa butter melts and recrystallises on the surface, or **sugar bloom**, when damp dissolves the sugar and it recrystallises. Both are **completely safe** —

Bread goes mouldy fast because it holds **a lot of moisture**, and the mould spores already floating in the air find it a perfect home. The fix: **away from heat and damp**, and in **the freezer** if it is more than…

Rice burns on the bottom because **the heat concentrates at the base** and the liquid runs out before the grain is cooked. The fix is three things: **a heavy-based pot** to spread the heat, **very low heat** after the first boil, and **the right liquid ratio** for the type of rice.

Cutting an onion breaks its cells, releasing an enzyme that reacts with sulphur compounds to produce **propanethial S-oxide gas**. The gas reaches the eye and turns into a weak sulphuric acid, and tears are simply a defensive reflex to wash it off the eye's surface.

The essential difference is **the pulse**: Egyptian taameya is made from **split dried broad beans**, and Levantine falafel from **chickpeas** (sometimes a mix of both). That makes taameya **greener inside and softer**, and falafel **paler and firmer**.

The rule that governs the choice of meat: **a muscle that works hard is tough and full of collagen, so it needs long, slow cooking**. A muscle that does not work is already tender, so it needs **high heat and a short time** — and long cooking ruins it.
