For precooked semolina couscous, a very common starting point is 1 part couscous to 1 part boiling liquid by volume, followed by about five minutes covered off the heat. But that ratio is not universal: brands and grain sizes absorb different amounts.
Food Network uses 1:1, while Near East and Barilla publish product-specific ratios that differ from it. The instructions on your package therefore take priority.
Couscous is not cooked like rice
Instant or precooked couscous has already undergone processing before it reaches your kitchen. At home it usually needs hydration with very hot water or broth rather than prolonged simmering.
Utah State University Extension specifically notes that couscous is an exception to its general grain-cooking ratios and recommends following package directions.
Why do brands give different ratios?
Granule size, degree of precooking, initial moisture, and formulation change how much liquid is required. Near East, for example, lists 3/4 cup couscous with 1 cup liquid for one preparation, while Barilla gives 80 ml liquid per 100 g couscous.
Those instructions are not necessarily contradictory because a volume ratio is not the same as a weight ratio and the products themselves are not identical.
How to use the 1:1 starting point
If you have plain couscous with no clear directions, equal volumes of couscous and liquid are a reasonable place to start. Bring water or broth to a boil, season it, pour it over the couscous or stir in the couscous, and immediately remove from heat.
Cover and leave for about five minutes. Steam and hot liquid hydrate the granules without continued boiling.
Why does couscous become clumpy?
Too much liquid leaves free water between granules and can create a pasty texture. Constant stirring during hydration also disrupts the surface and encourages starch to glue particles together.
Pressing the couscous down with a spoon makes clumping worse. The goal is to hydrate and then separate, not work the mixture like mashed potatoes.
Use a fork to fluff, not mash
After resting, run a fork gently through the couscous to lift and separate grains. A small drizzle of olive oil or a little butter can improve lubrication and flavor.
Do this while the couscous is still hot and before folding in wet ingredients, so the granules are evenly separated first.
What if the couscous is too dry?
If the center still feels hard, add one or two tablespoons of very hot water or broth, cover again, and wait a few minutes. Small corrections prevent you from jumping from dry to mushy.
Next time, increase the liquid slightly, especially if the brand has larger or less precooked granules.
What if it is too wet?
Uncover and fluff to release steam. Spreading the couscous on a wide tray for a few minutes helps excess moisture evaporate.
Do not try to fix it with prolonged high-heat cooking, which can make the bottom stick and the granules softer.
Pearl couscous uses a different method
So-called pearl or Israeli couscous consists of much larger pasta balls and is generally boiled more like pasta or rice. Do not automatically apply the five-minute 1:1 hydration method.
The practical rule: for standard precooked couscous, 1:1 by volume is a useful fallback when no directions are available, but the package wins. Boiling liquid, a covered rest, and fork-fluffing are the keys to separate grains.
For repeatable results, pay attention to the exact product and technique rather than only the recipe name. Variety, grain size, water amount, agitation, and temperature can all substantially change final texture.

Frequently asked questions
How much water per cup of couscous?
One cup liquid per cup couscous is a common starting point for precooked couscous, but check the package because brands vary.
Why does couscous clump?
Common causes are too much liquid, excessive stirring during hydration, and failing to fluff the grains afterward.
Do you boil couscous for five minutes?
Standard precooked couscous is usually covered with boiling liquid and left off the heat for about five minutes.
