Because honey is a supersaturated sugar solution — it holds more sugar than water can normally dissolve — and that state is inherently unstable. Crystallisation is the sugar coming out of solution.
All three are fruit preserved with sugar. The difference is which part of the fruit ends up in the jar. Jam is made from crushed or chopped whole fruit cooked with sugar. It contains pulp and often
Gluten is not a single substance. It is a network formed when two proteins in wheat — glutenin and gliadin — meet water and are worked together. Neither does much alone; combined and hydrated, they
To remove surface starch. Milling and handling leave loose starch powder on the grains, and if it goes into the pot it gelatinises in the cooking water and makes the finished rice sticky and clumped.
The white or greyish film is bloom, and it is not mould. There are two distinct kinds, with different causes. Fat bloom is the common one. Cocoa butter can solidify into several different crystal
It is iron sulphide, formed by a harmless chemical reaction between the yolk and the white — and it is a reliable sign that the egg was cooked too long or too hot. Egg white contains sulphur-bearing
Fermentation is the controlled conversion of sugars and starches by microorganisms — bacteria, yeasts or moulds — into acids, alcohol or gases. It preserves food because those products create
Because it is the only opportunity to season the pasta itself rather than just what goes on top of it. Salt added to the sauce sits on the surface; salt in the cooking water is absorbed into the
The grades describe how the oil was extracted and how much it has degraded — not, as many assume, how the olives were pressed or how many times. Extra virgin is the top grade. It is mechanically
To develop gluten — the protein network that traps gas and gives bread its structure. Without it, dough cannot hold the bubbles that yeast produces, and the loaf collapses into something dense. Wheat
Under rally scoring, a point is awarded on every rally regardless of who served. Under the older side-out systems, only the serving side could score, and winning a rally as receiver merely won you
Because the body runs out of its most accessible fuel. "The wall" is the sudden, severe fatigue that many marathon runners experience somewhere after 18 to 22 miles, and it has a specific
In both sports, a Grand Slam is the set of four most important annual tournaments — and, in its strictest sense, winning all four in the same calendar year. Tennis has the Australian Open in January,
Chess uses the Elo rating system, devised by the physicist Arpad Elo. A rating is a number that estimates playing strength, and it moves after every game based on the result and the strength of the
Three separate competitions that English clubs play in simultaneously, run by different bodies with different formats. The Premier League is a league. Twenty clubs each play every other club twice,
A mathematical method for resetting the target in a rain-affected limited-overs match, so that a side batting second is asked for a fair score given the overs and wickets it actually has. The problem
Players score by potting balls in a set order, and the colours are worth different amounts. The table holds 15 reds worth one point each, and six colours: yellow 2, green 3, brown 4, blue 5, pink 6,
A triathlon is a swim, then a bike ride, then a run, completed in that order without a break — the clock runs through the transitions. There are several standard distances. Super sprint — 400m swim,
The numbers describe how outfield players are distributed from defence forward. The goalkeeper is never counted, so the digits always add up to ten. means four defenders, four midfielders, two
The Video Assistant Referee can only intervene in four categories of decision, and only when there has been a clear and obvious error or a serious missed incident. The four are: Goals — and any part
Points are awarded to the top ten finishers in each Grand Prix, on a sliding scale, with additional points available in some circumstances. The race scale is 25-18-15-12-10-8-6-4-2-1 for first
Leg before wicket dismisses a batter whose body — usually the pad — stops a ball that would otherwise have hit the stumps. Without it, batters could simply stand in front of the wicket and block
In its original logical sense, begging the question means assuming the truth of the thing you are trying to prove. It is a form of circular reasoning, not a way of saying "this raises a question".
A simile compares two things using like or as. A metaphor states that one thing is another. Her argument was like a hammer. (simile) Her argument was a hammer. (metaphor) The distinction is not
It depends which side of the Atlantic you are writing for, and this is one of the clearest differences between American and British style. American style puts commas and full stops inside the closing
Both are abbreviations formed from initial letters. The difference is how you say them. An acronym is pronounced as a word: NASA, NATO, scuba, laser, radar. An initialism is pronounced letter by
The most widely used convention is to spell out numbers one to nine and use digits from 10 upward. Some style guides set the cut-off at one hundred instead, so the first thing to establish is which
Use that for clauses essential to the meaning of the sentence, and which — with a comma — for clauses that add extra information. The report that we published yesterday is online. — identifies which
Farther refers to physical distance. Further refers to degree, extent or additional amount. The station is farther than I thought. (measurable distance) We need to discuss this further. (extent, not
A modifier that is not attached to the thing it is supposed to describe, so the sentence appears to say something the writer did not mean. Walking to the station, the rain started. Grammatically,
The general rule: capitalise a job title when it comes immediately before a person's name as part of that name, and lowercase it when it stands alone or follows the name. We met Chief Executive Amara
Three marks of different lengths doing three different jobs. Most writing uses only the first, which is why the others look unfamiliar. Hyphen ( - ) — the shortest, and the one on the keyboard. It
Lay needs an object — you lay something down. Lie does not — you lie down yourself. I lay the book on the table. (the book is the object) I lie on the sofa. (no object) That much is manageable. What
In the active voice, the subject does the action: the committee rejected the proposal. In the passive voice, the subject receives it: the proposal was rejected by the committee — or, with the actor
Three words that sound identical and mean entirely different things. Each has one job. Their is possessive. It shows something belongs to a group. Their car, their idea, their fault. There indicates
Mineral oil is refined directly from crude petroleum. Synthetic oil is engineered — either heavily processed from petroleum stock or built from chemically synthesised base molecules — so that the
The colour is a reliable guide to what is being burnt that should not be, and it narrows the diagnosis considerably. Thin white vapour that disappears quickly is normal, especially on a cold morning.
Limp mode — also called limp-home mode or reduced power mode — is a protective state the engine management enters when it detects a fault serious enough to risk damage. It deliberately restricts
In most cases the battery. A fob battery typically lasts two to four years, and the failure is usually gradual — reduced range first, then intermittent operation, then nothing. The batteries are
The three differ in where the energy comes from and how much of your driving can be electric. The practical question is not how they work but which suits your journeys. A hybrid — often marketed as
Several things degrade at once, and most of them are avoidable with a little preparation. The battery is the usual first casualty. Modern cars draw a small current continuously for alarms, keyless
Because brake discs are made of cast iron, which is deliberately not corrosion-resistant, and there is nothing protecting the surface between uses. Cast iron is chosen for discs because it handles
The diesel particulate filter is clogged and the car has not been able to clean it. The filter traps soot from the exhaust, and it is designed to burn that soot off periodically — a process called
No. Engine braking is a normal, designed behaviour, and in most respects it is gentler on the car than using the brakes. Engine braking is the slowing that happens when you lift off the accelerator
Only if your car requires it or is tuned to take advantage of it. For most cars, higher-octane fuel provides no benefit and the extra cost is wasted. Octane rating does not measure energy content or
Alignment is the set of angles at which the wheels sit relative to the road and to each other. When those angles drift out of specification, the tyres are dragged rather than rolled, and they wear
Because air contracts as it cools, so the pressure inside a sealed tyre genuinely falls — no leak required. The rule of thumb is roughly 1 psi lost for every 10°F drop, or about 0.07 bar for every
Cooler than most people serve it. "Room temperature" is a phrase from an era of unheated stone houses, where a room was around 15°C. A modern heated room at 21°C is well above the point where most
Natural cocoa is acidic. Dutch-process cocoa has been treated with an alkali to neutralise that acidity. The difference changes colour, flavour and — critically for baking — how the cocoa reacts with
Yes, though "goes off" overstates it for most wines. What happens is oxidation: exposure to air changes the flavour, first improving many wines and then progressively flattening them. Oxygen reacts
