Measuring pointers

Make sure you have the right tools

Have a set of measuring teaspoons, a set of measuring cups for dry ingredients and liquid measuring cups ranging from a one-cup to four-cup capacity. While it’s not absolutely necessary to own, a food scale is useful to have, as it allows you to make recipes that list ingredients by weight. This is particularly useful for baking, which often demands exact measurements.

Level off your dry ingredients for the right measurement

Unless the recipe calls for “a heaping tablespoon” or “a generous cup,” you’ll want to level off the dry ingredients you’re measuring. That just means taking the flat side of a butter knife and running it across the top of the full cup or spoon, so any excess is sloughed off.

Use the right cups for dry and wet ingredients

At some point, most home cooks have dumped flour into a liquid measuring cup or measured milk in a dry measuring cup. Some recipes are forgiving enough that you can get away with it. But others, especially if you are baking, can be completely ruined. Technically dry and liquid measuring cups measure the same, but it’s not a perfect science. A liquid measuring cup doesn’t allow you to level off your dry ingredients, so it’s really hard to measure exactly. And measuring wet ingredients in a dry cup is difficult, since measuring right to the rim can lead to spillage.

What's the difference between an ounce and a fluid ounce?

If a recipe lists dry ingredients in ounces, you’ll need a kitchen scale to measure it. But if a recipe lists a wet ingredient in ounces, you can measure it in a liquid measuring cup. Ounces are measured by weight, and fluid ounces are measured by volume. While eight ounces of water can be converted to one cup of water, the same can’t be done for eight ounces of sugar -— make sense?

How to measure baking ingredients properly

What exactly does it mean when a recipe calls for packed light brown sugar? As opposed to a “scoop and shake” method, packed brown sugar means that you need to use the measuring cup to scoop the brown sugar and then use your hand to pack it tightly before adding it to the mixing bowl. If a recipe calls for one cup of sifted flour, that means you need to pre-sift the flour before measuring it.
