Breadmaking machines

Freshly made bread is the best thing since—well, the best thing since sliced bread! The only trouble is, it takes time and effort. Most people have never made bread in their lives and would never dream of doing so, but the recent invention of automatic breadmaking machines has started to change all that. Now, millions are turning their kitchens into bakeries and enjoy their own freshly baked loaf each day at a fraction of the cost they'd pay in a store. What's the big attraction of bread-making machines? What are they like and how exactly do they work?

Unfortunately, this early model has an opaque lid so you can't watch the ingredients slowly transform into a delicious loaf, but most models now have glass lids so you can watch progress in real time. A glass lid means you can spot any problems and abort your baking session; with an opaque lid, you might have to wait five hours to discover that your loaf's a disaster (something a glass lid might have revealed several hours earlier). There is a little dark vent in the center of the lid through which you'll see steam (and smell the aroma of freshly baked bread) escaping!

How to make bread (the old way)

Bread is one of the world's oldest and most versatile foods. Just think of all the different types of bread (everything from a basic sliced white loaf to a really fantastic ciabatta or foccacia) and all the different ways we use dough (from simple loaves to rolls and pizza bases). Delicious!

Eating bread is an awful lot easier than making it—and that's because bread-making is necessarily a time-consuming process. Even with the help of an automatic breadmaker, it still takes several hours to make a loaf because it takes that long for the yeast to do its job.

The basic process of making a loaf involves five distinct stages:

The five stages of making bread: 1) Mixing; 2) Kneading; 3) Rising; 4) Knocking down and proving; 5) Baking.

  1. Mixing: You take flour, yeast, water, fat, sugar, and salt and mix them together to make dough.
  2. Kneading: You have to beat and bash the dough around to make it stretchy and elastic. Without kneading, your dough won't rise and you won't get a decent loaf.
  3. Rising: Now you leave your dough in a warm place to rise for an hour or more. During this stage, the yeast does its job. Air enters the mixture and makes the dough plump up to about twice the size.
  4. Knocking down and proving: Some bakers believe you should repeat the rising process a second time to produce a more even loaf. First you bash the dough about to knock the air out of it (which is called knocking down). Then you leave the dough to rise a second time in a tin (which is called proving).
  5. Baking: Finally, you put the dough in a tin, place the tin in your oven, and bake.

How a breadmaking machine works

The great thing about an automatic breadmaker is that it does all these processes for you. A breadmaking machine is essentially a compact electric oven that will hold a single, large bread tin.

Photo: Looking straight down into the breadmaker with the lid open. You can see it's really just a compact oven. There are two heating elements at the side for baking the bread. The round thing in the middle at the bottom is the electric motor that does the kneading.

The tin is a bit special: it has an axle at the bottom that connects into an electric motor underneath. A small metal paddle clicks onto the axle inside the tin. The axle is held by a waterproof seal so none of your bread mixture will escape.

Photos: Top: The kneading paddle in place at the bottom of the tin. Note how the tin has a useful wire handle so you can haul it up out of the machine while it's still hot. Bottom: What the kneading paddle looks like when you remove it. As this turns around at speed, it flings the dough around and kneads it.

So how does it all work? First, you put your paddle in the tin. With the tin out of the oven, you measure out your ingredients and load them up. All you have to do then is pop your tin in the oven, select the program you want using the electronic control panel, close the lid, and wait. If your breadmaker has a glass lid, you can watch what it's doing. If the lid is opaque, you'll have to listen and use your imagination. One of the first things you'll hear is the machine's motor whirring as the paddle spins round, kneading the dough. Then everything will go quiet during the rising phase. Then you'll hear more kneading and another period of quiet during the proving. Finally, the oven will switch on, you'll see steam coming up through the exhaust vent, and you'll start to smell the delicious aroma of baking bread a few minutes later. The basic breadmaking process is largely automatic, but most machines come with recipe books for making more advanced types of dough.

Some breadmakers have other features, such as a built-in memory so they can survive short power outages ("blackouts") of a few minutes: they remember what they were doing and continue when the power returns. Most breadmaking machines also have the ability to make a delayed start, so you can put the ingredients in before you go to bed and wake up to a fresh-baked loaf in the morning. (It's worth noting, however, that if you leave a loaf in a hot machine after it's done it will go on cooking and the crust will become noticeably harder—maybe to your taste, maybe not.)

What's inside a breadmaking machine?

Here's an illustration of one of Panasonic's original breadmaking machines (taken from what I believe is the earliest patent they filed in the United States), which is very similar to the machine I've photographed for this article.

Artwork courtesy of US Patent and Trademark Office. There's lots more to a breadmaker than the bits you can actually see. If you're really interested in the technical specifics, do take a look at the original patent.

What are all the bits and what do they do?

  1. Baking tin cover integrated into folding lid.
  2. Folding, hinged lid contains steam exhaust vent in the center.
  3. Exhaust port allows steam to escape from baking tin and flow out through lid.
  4. Air vent allows air into the dough to help it rise.
  5. Power supply lead.
  6. Hole where baking tin screws securely into place containing, at its center, the motorized axle that turns the kneading paddle.
  7. Plastic outer case insulates the oven and makes the breadmaker safe to touch during operation.
  8. Simple LCD display and wipe-clean touch-control panel.
  9. Recessed groove where the bottom of the lid locks in.
  10. Removable baking tin will bake a single loaf at a time.
  11. Detachable kneading paddle clicks onto an axle slotted through the center of the tin in a waterproof seal.
  12. Tongue around edge of lid fits securely into groove (9) in bottom part of machine to ensure heat is retained.

What kinds of bread can you make with a bread machine?

Breadmaking machine control panel

Most breadmakers have numerous different programs for making many different kinds of loaf. You can make white bread, wholemeal, or special loaves by using different kinds of flour and varying the other ingredients. You can see the various options that this breadmaker offers on its display panel (from the top: basic, wholemeal, multigrain, French, pizza, and bake only). For different breads, you simply put a slightly different mix into the tin at the start and select a different program from the display, and the breadmaker will handle different kneading, rising, and baking times, and so on automatically. (So French loaves get a longer rising time, wholemeal loaves get more preheating, sweet breads have longer kneading and rising times, and dark crusty breads get extra baking time.) Some breadmakers also offer a "fast-bake" (energy-saving mode) that delivers your loaf in about half the time, but you'll get a somewhat less polished performance: not always such an even mix or spectacular rise. Baking bread takes time and patience and you can't expect perfect results if you rush it.

Photo: Forget boring old white and brown: see your new breadmaker as an opportunity to make the loaves you like most, cooked exactly how you like them. If you prefer seeded loaves, just add a mix of your favorite seeds (linseed, poppy, sesame, sunflower, or whatever you like) to the ingredients. Recipes tailored to breadmakers are easy to find online (and I've listed a few good books in the references down below).

How easy are breadmakers to use?

Very! Programming a breadmaker is a simple operation:

  1. Select the type of bread (basic, wholewheat, multigrain, French, or pizza).
  2. Select the bake mode (bake, bake rapid, sandwich, dough). This varies the sequence of mixing, kneading, rising, and baking. For example, in dough mode, the machine stops without actually cooking the dough. At this point, you open up the lid, remove the dough, and then take it out for your pizza, croissants, or whatever. (You have to bake those in your oven, but the breadmaker helps you by preparing the dough.)
  3. Select the size of loaf (large, medium, or small).
  4. Select the type of crust you want.
  5. Press the TIMER button. The display shows the total time the loaf will take to prepare and cook.
  6. Press the START button and the countdown to a delicious loaf begins!

When you're loaf is done (in anything from two to six hours but typically about three to four), you very carefully lift the lid, pull the hot tin out of the breadmaker's oven, tip out the loaf, and let it cool down. All you have to do in the way of cleaning is wash out the tin (which is helpfully nonstick) and the paddle—which takes about 30 seconds.

Do breadmaking machines save you money?

You're probably wondering how much it costs to make a loaf this way. It's impossible to say, really, because it depends on the exact ingredients you use. But with the price of flour soaring and bakeries charging ever more for their loaves, my guess is that a machine like this would easily pay for itself in a year or two, giving you quite delicious bread at the same time.

Who invented breadmaking machines?

You might be thinking breadmaking machines are a relatively recent innovation, developed in the last 20–30 years or so? It's true that small household breadmakers only became popular in the 1990s, thanks to companies such as Panasonic (a brand name of Matsushita Electric Industrial Co., Ltd. of Japan), who pioneered the one-loaf, home breadmaking machine in 1986. But if you think about it, breadmaking machines are obviously much older than this. The mass-produced sliced loaves many people eat aren't all produced by hand! In fact, mechanical breadmaking machines have been around since at least the early 20th century.

The earliest breadmaking machine I've found—the one shown here—was invented in 1903 by Sarah Stearns of Redlands, San Bernardino, California and patented the following year.

How does it work? Flour (yellow) sits in a hopper at the top (green). When you turn the handles (gray) on the side, it rotates a paddle (orange) inside the hopper that sifts the flour through a mesh and down onto the rollers (turned by gear wheels). Dough passes between the rollers (red) on a sliding tray with flanges at the edge (darker red) supported by a sturdy frame (blue). What we have then is really a dough-kneading machine; the handles (which work like levers) and gears help to make kneading far easier than it would be by hand. Probably if you had hundreds of loaves to prepare, something like this would save a huge amount of time. Unlike a modern breadmaking machine, it doesn't cook the loaves as well—and you still have to supply the energy for kneading by cranking those handles.
