How do I make a vegetable stock that actually tastes of something?
Why vegetable stock is usually watery and sweet, the four ingredients that give it savour, and why it needs a fraction of the cooking time of a meat stock.

The proportions of mint, sugar, vinegar and water, why the boiling water step matters, and how long it keeps once made.

The grip, the blade angle and the sawing motion that separate skin from flesh cleanly — plus the two cases where you should leave the skin exactly where it is.
intermediate5 min4 min readIs vacuum sealing food actually worth it?
What it genuinely improves, what it does not, and the safety caveat people miss.
beginner10 min3 min readWhat does egg actually do in a recipe?
Eggs do six different jobs and most recipes use two or three at once. Working out which job yours is doing is the only way to substitute, scale or troubleshoot it sensibly.
beginner7 min4 min readWhich lentils should I use for what?
Six lentils sold in the UK, what each one does at the end of its cooking time, and why the same recipe gives a salad with one and a purée with another.
beginner5 min3 min readWhich sugar should I use for which bake?
Sugar is not one ingredient. Crystal size decides how well it aerates, and molasses content decides moisture, colour and flavour — so swapping one for another changes the bake in predictable ways.
beginner8 min3 min readWhy did my cake rise unevenly and come out lopsided?
A cake that is high on one side has been heated unevenly, filled unevenly, or baked in an oven that is not level. The tilt itself tells you which — and where the high side sits is the clue.

A leaking tart case has a hole in it, and the hole was almost certainly there before the filling went in. How to find and seal cracks after blind baking, and the lining faults that produce them.

Sticking is a temperature and contact problem, not a fat quantity problem. The five causes, in the order that finds it fastest, and how to get a stuck tray off intact.

Browning is oxidation and bitterness usually comes from the blender or the oil — how to prevent both, and what to substitute when you have no pine nuts or no basil.

The three causes of gritty, crystalline jam, which of them you can undo, and how to stop it happening again.

The water comes out of the cauliflower after the sauce is on it. Three ways to get ahead of that, plus the separate faults that make the sauce split or go grainy.
beginner15 min3 min readWhy is my fudge grainy, or too soft to cut?
Fudge is controlled crystallisation. Grainy fudge crystallised too early or too coarsely; soft fudge never reached the temperature that removes enough water. Both are thermometer problems.

Fat and sugar both slow yeast down and both interfere with gluten, so an enriched dough is genuinely harder to raise than a lean one. What is normal, what is a fault, and how to tell them apart.
intermediate12 min4 min readCan I freeze bread dough, and at what stage?
Yes, and the stage you freeze at decides how much work is left when you thaw it. After shaping is the most useful point for most people; after the first rise is the most reliable.

A small, expensive, fast-cooking joint where five minutes is the difference between perfect and ruined — the sear, the oven stage and the temperature to pull it at.

Grainy hummus is a chickpea problem, not a blender problem. Cooking them past the point that feels right, and the bicarbonate step that dissolves the skins entirely.

Pale, unbrowned, rolled and barely set in the middle. The pan, the temperature and the constant agitation that separate a French omelette from an ordinary folded one.

Which plant milks behave in a roux and which split, the fat to use instead of butter, and how to get back the savoury depth that dairy was providing.
beginner15 min4 min readHow long should I actually preheat the oven?
Longer than the indicator light suggests. The light responds to the air temperature; the walls, shelves and any stone or tray inside take far longer, and it is those that supply the heat a bake needs at the start.

What monosodium glutamate actually is, where the health scare came from and what the evidence says now, and how to use it in an ordinary kitchen if you decide to.
