Which one should you buy?

A simple, accurate stainless dial thermometer is all most bakers need, and it costs less than a bag of good flour. Here's what I'd point you to:

Most home ovens are off by a little, and some are off by a lot. If your cookies burn on the bottom or your cake sinks in the middle, the recipe may not be the problem. The oven might be 25 degrees hotter or colder than the dial says.

An oven thermometer is one of the cheapest, most useful things you can own. You put it in, you wait, and you find out what your oven is really doing. Then you can adjust the dial to match and stop blaming yourself for things that were never your fault.

What your oven is really up to

An oven doesn't sit at one steady temperature. It heats past the number you set, switches off, cools down below it, then switches back on. Round and round it goes, all the time it's on. A swing of around 25 degrees either side can be perfectly normal.

So what you're really after is the average. If the needle wanders between 325°F and 375°F with the dial at 350°F, your oven is fine. If it wanders between 350°F and 400°F, it's running about 25 degrees hot, and that's worth knowing.

It matters most for bakes that rely on a burst of heat or a precise set: popovers, Yorkshire puddings, soufflés, choux pastry, cheesecake. A few degrees can be the difference between a proud rise and a sad flop.

The other thing to know is that the beep lies. Ovens often announce they're preheated well before the walls and racks have caught up.

CDN ProAccurate DOT2 at a glance

To be fair about it: the face is small and fairly dark, so it isn't the easiest thing to read through an oven door, and like any dial it's slow to respond. You'll want a torch, or a quick peek with the door open.

What to look for in an oven thermometer

• Accuracy over looks. A big, pretty dial is no use if it reads wrong. Cheap dials can be well out.

• A sensible range. At least 150°F to 550°F covers everything from proving bread to roaring-hot pizza.

• Stainless steel. It won't mind the heat and wipes clean.

• A hook and a stand. So you can hang it on a rack or stand it up, wherever you need it.

• A readable face, or a display outside the oven. If you hate squinting, a digital probe with the screen outside is worth the extra money.

The DOT2 wins on accuracy and build. It loses a point on readability, which is why I've suggested the ChefAlarm for anyone who wants an easier life.

Who it suits, and who should skip it

Good for you if

• You bake, full stop

• Your bakes brown unevenly or take longer than the recipe says

• You've just moved house, or you're using an old or rented oven

Skip it if

• You'd rather read the temperature without opening the door: go for a digital probe like the ChefAlarm

• Your eyesight makes small dials a struggle

How to get the best from it

Test it properly

Start with an empty oven. Put the thermometer in the centre of the middle rack and set the oven to 350°F, or to whatever temperature has been giving you trouble.

Be patient

Ignore the beep. Wait at least 30 to 40 minutes from switching on, because a dial thermometer takes its time to catch up. Then take a reading, wait ten minutes, and take another. Do it three or four times and you'll see the oven's swing, and its average.

Then adjust

If the average is 25 degrees hot, set the dial 25 degrees lower when you bake. Many modern ovens also have a calibration setting tucked away in the menu; the manual will tell you how.

Check the corners

Once you know the middle, try the back and the sides. Most ovens have a hot spot, and knowing where it is tells you when to turn your tray.

Looking after it

• Wipe it, don't soak it. A damp cloth on the steel and the glass is all it needs.

• Don't leave it in for good. Pop it in when you want to check, then take it out. It stays cleaner and lasts longer.

• Take it out for self-clean. The temperatures of a cleaning cycle go well past what it's built for. Check your oven's manual.

• Mind the glass. A knock on the oven door frame can crack the lens.

The one rule

Judge the average, not one reading. A single glance can catch the oven at the top or bottom of its swing and send you chasing a problem that isn't there.

Questions people ask

How far off are home ovens?

Many are within a few degrees on average. Some are 25 degrees or more out. Swinging up and down around the set temperature is normal; an average that's well off is the problem.

Where should I put an oven thermometer?

In the centre of the middle rack for your main test. Move it around afterwards to find hot spots.

How long should I wait after preheating?

Give it 30 to 40 minutes from switching on, and take several readings, not just one.

Dial or digital?

A good dial is accurate and cheap, but slow and harder to read. A digital probe with the display outside the oven is quicker and easier, and costs more.

My oven runs hot. What now?

Set the dial lower by the difference, or use your oven's calibration setting if it has one. If it's wildly out, or it won't hold a steady average, it's time to call an engineer.
