How to Measure Flour Correctly, for perfect baking results.

Perhaps nothing in baking is more important than measuring the flour correctly and precisely. Many baking pitfalls start right there.

One of the most common comments I get from readers who try bread recipes in particular, is that the dough is too dry or didn’t rise enough or too slowly in the proofing stage. The reason is often over measuring the flour.

When I recently posted an incredibly easy way to make No Knead Bread, the questions and comments came again. I decided it was time to talk about best practices when it comes to measuring this most common baking ingredient.

The difference is real.

Cooking is different than baking. Many non-baking recipes have a little wiggle room to make adjustments. A little more of this, less of that, or even sometimes leave an ingredient out altogether, many recipes can be quite forgiving.

Baking is not like that.

Baking is precise, but our North American volume/cup measurements often are not. Many of our followers from the UK, Europe and other parts of the world, weigh all of the ingredients in baking, which is far more precise and leaves little room for error.

Why we did not follow along with that system here in North America confounds me. It confounds our readers outside North America as well, as I have heard from them many times over the years of writing this blog.

How to measure flour correctly is important.

Why is measuring method important? The photo below demonstrates how wildly different the weights of a cup of flour can be.

How you measure flour is important. It can result in mis-measurement of up to 34%.

The cup of flour on the right was scooped directly out of the bag or flour container and levelled with the back of a knife. The cup of flour on the left was spooned into the cup and then levelled with the back of a knife. 

The difference in weight is actually 34%. So if you are measuring flour by scooping it, you are compressing in the flour in the cup.

This is often compounded by many who press the top of the measuring cup against the bag or container they are scooping it from. Yes, that can make the process a little less messy, but you may be adding up to 1/3 more flour than the recipe actually calls for.

This can cause bread to be drier, cakes to be denser, biscuits to be less flaky, and cookies too brittle. If you have a scale, measure a proper cup of flour and it should be 140 grams give or take a gram or too.

The right technique.

The proper technique is to spoon the flour into the cup until it is overflowing, then run the back of a knife across the top to level it. This will result in perfectly measured flour every time.

One online resource , to which I often refer our friends outside North America, is a conversion guide from Cooks Illustrated online. They have some common baking ingredients converted from cups to grams, which is very useful to bakers overseas.

Find that conversion guide here.

Of course our most popular bread recipe ever is my decades old recipe for the Best Homemade White Bread. That recipe has received many, many rave reviews over the years. 

Many folks have told me it is the recipe that succeeded for them when others had failed. Be sure to give that one a try too.

I've always measured the flour right in the bag like you say; I didn't always get good results. After 50 years It's the first time someone shows the right way of doing it. I can't wait to make a recipe to try your method. I bet it really makes a difference. Thanks so much for taking the time to explain.

There's a far better way (no pun intended), weigh the flour on proper scales, scooping/spooning are incredibly messy ways (as seen in the pics above) & so hit/miss! Use Imperial or Metric, you can't go wrong, one of the first acquisitions for a cook should be a set of weighing scales, far more accurate than using volume approximations.

I have a question about your coconut cream pie (couldn't find the comment section under the coconut cream pie). You have talked about using flour and not cornstarch because of the texture. I use cornstarch because my daughter has Celiac Disease and can't eat flour. Is there another substitute that would work besides cornstarch? Thanks!

I, as well, wish we'd converted everything over to metric and weighed our ingredients for our recipes. I think at the time that converting to metric measurements in the Canadian household was proposed, it was a lack of experience of most people with it that pushed back at it. And the meat producers in our country were afraid of sticker shock in grocery stores. But anyone who has worked with metric will tell you that there is no easier system for measurement. I sometimes wonder if another attempt at proposing this as our primary system would meet with more success. .

The only correct way to measure flour Is with scales. Any other method Is innacurate including This one.
