Question 1

What is gluten and what does it do?

Accepted Answer

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 form long elastic strands.

That network gives dough two properties that matter. **Elasticity**, from glutenin, is the tendency to spring back when stretched. **Extensibility**, from gliadin, is the ability to stretch without tearing. Bread needs both: enough elasticity to hold its shape, enough extensibility to expand as gas is produced.

In practice gluten is what lets baked goods hold gas bubbles. Yeast or a chemical raising agent produces carbon dioxide, the gluten sheets trap it, and oven heat sets the structure. It is the reason bread has an open crumb rather than being a solid brick.

Different flours contain different amounts. **Strong** or bread flour has high protein, around 12–14%, for chewy, well-risen loaves. **Plain** or all-purpose sits around 10–12%. **Cake and pastry flours** are lower, around 7–9%, deliberately — for a tender crumb you want *less* gluten, which is why overmixing a cake batter makes it tough and why pastry is handled as little as possible.

Gluten also occurs in barley and rye, in related forms.

For people with **coeliac disease**, an autoimmune condition, gluten causes damage to the small intestine and strict lifelong avoidance is medically necessary. Non-coeliac gluten sensitivity is a separate and less well-characterised condition. Anyone suspecting either should seek testing before removing gluten, since testing is unreliable once it has already been cut out.

Gluten-free baking substitutes structure with gums, starches and eggs.

Question 2

Why does bread dough need kneading?

Accepted Answer

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

Question 3

Why does bread dough need to prove twice?

Accepted Answer

Because the two rises do different jobs. The first develops flavour and structure; the second creates the final texture of the loaf. The first prove, sometimes called bulk fermentation, is the long

Question 4

Why do batters need resting?

Accepted Answer

Two things happen while a batter stands, and both improve the result — which is why the instruction appears in recipes for pancakes, Yorkshire puddings, crêpes and batters for frying. Gluten relaxes.

Question 5

What is the difference between flaky and short pastry?

Accepted Answer

How the fat is distributed — in visible layers or rubbed evenly through the flour — and it produces two completely different textures from nearly identical ingredients. Shortcrust — "short" means

Question 6

Why does sourdough need a starter, and what makes it sour?

Accepted Answer

A sourdough starter is a living culture of wild yeasts and lactic acid bacteria maintained in a flour-and-water mixture. It both raises the bread and produces the flavour, and those are two separate

Question 7

Why is my cake dense instead of light?

Accepted Answer

Almost always a problem with trapped air — either not enough was incorporated, or it escaped before the structure set. A cake rises on gas, and dense cakes are cakes that lost their gas. The causes,
