Why cooking works, not what to cook
Something went wrong, or you want to know why it goes right. FoodHQ explains what is actually happening in the food — and shows the evidence behind every statement, including when that evidence is thin. It is not a recipe site: no ingredient lists, no dinner suggestions.
Something has gone wrong
What it looks like, what caused it, and what stops it next time.
-
Fruit and vegetables
Black basil leaves
Basil blackening in patches, usually within a day or two of going into a refrigerator.
-
Bread not rising
Why bread dough fails to rise, how to tell if the yeast is alive, and whether a slow dough can be saved.
-
Pesto turning brown
Why basil browns in pesto, which step causes it, and how to keep a jar green for days.
-
Burger falling apart
Why home-made burgers collapse, why egg and breadcrumbs are the wrong fix, and what actually holds a patty together.
Learn a technique
How each way of cooking works, what it does to food, and where it goes wrong.
-
Method
Baking
Dry-heat cooking in an enclosed oven, where a starch or protein matrix sets from the inside while the surface dries and browns.
-
Method
Boiling
Cooking submerged in water at its boiling point, where the liquid holds a ceiling temperature the food cannot exceed.
-
Method
Deep frying
Cooking by full immersion in hot fat, where the oil is both the heating medium and part of the finished food.
-
Air frying
What an air fryer really does, why it is not frying, what it does better than an oven, and its real limitations.
-
Barbecuing
The difference between grilling over fire and true barbecue, why a two-zone fire changes everything, and how to stop burning the outside.
-
Basting
Whether basting keeps meat moist, what it genuinely achieves, and the two situations where it is worth doing.
Build your skills
The things that make everything else in the kitchen easier.
-
Fermented or pickled?
The real difference between fermented vegetables, vinegar pickles, quick pickles and shelf-stable jars, and what each is good for.
-
How to balance a dish
A diagnostic method for food that tastes flat, heavy, sharp or dull, and what each fix actually does.
-
How to brown food properly
Why browning creates flavour, the four conditions it requires, and the mistakes that stop it happening.
-
How to build flavour
Why the order ingredients go into a pan matters, what browning, blooming and deglazing contribute, and how depth is actually constructed.
-
How to choose a cooking oil
Which oils suit which cooking, what smoke point means and how much it matters, and which oils are for flavour rather than heat.
-
How to choose a preservation method
Every way of making food last, what each does to flavour and texture, and how to pick the right one for what you have.
Explore ingredients
What a food is, what it tastes like, how it behaves, and what to do with it.
Understand the science
The processes underneath — browning, starch, protein, crisping — explained.
-
Cooking science
Aeration
Gas is incorporated and stabilised within a structure, lowering density and changing mouthfeel.
-
Cooking science
Alcoholic fermentation
Yeasts convert sugars principally to ethanol and carbon dioxide.
-
Cooking science
Anthocyanin pH response
Anthocyanin pigments change colour with pH, shifting between red, purple and blue-green ranges.
-
Cooking science
Caramelisation
Thermal degradation of sugars alone, with no amino compound involved, producing colour and its own distinct aroma set.
-
Cooking science
Carryover cooking
Heat already stored in the outer layers keeps moving inward after the food leaves the heat, so the centre continues to rise.
-
Cooking science
Cell rupture on cutting
Cutting, peeling, grating and mashing break open cells that were keeping enzymes and their substrates apart.
Kit that earns its place
What a tool is for, when it helps, and when you do not need it.
-
Air fryer
What an air fryer actually is, what it does better than an oven, whether it is worth the counter space, and how to choose one.
-
Baking sheet
What makes a good baking sheet, why colour and thickness change results, and how many you actually need.
-
Blender
The difference between a jug blender, a stick blender and a food processor, which to buy first, and how to blend hot liquids safely.
-
Box grater
What the four sides of a box grater do, when to use a microplane instead, and a set of grating tricks that save real time.
-
Bread knife
Why a serrated blade cuts bread and a sharp straight one crushes it, what else it is for, and why it cannot be sharpened easily.
-
Cake tin
How tin size and material change baking, how to convert between tins, and which ones to own.
