Boil the water in a kettle or the microwave.
While the water is heating, add 1 cup of couscous, salt, and seasonings of choice to a large jar or container (with a lid). Pour 1 cup of boiling hot water over the couscous, stir, and cover so the couscous soaks up the seasoned liquid. Pro Tip: for a softer texture, add an additional 2 tablespoons water.
In ~5 minutes, the water will all be absorbed and the couscous will be plump and hydrated. Uncover and fluff with a fork. Alternatively, dump the couscous into a large bowl, fluff with a fork, add extra spices and fresh herbs (if using) then return to the jar.
Leftover couscous can be stored in the jar in the fridge for up to a week. You can freeze extra couscous for several months.
