You can typically find three different types of couscous at your grocery stores. Moroccan couscous is the tiniest and only takes a few minutes to cook. Israeli couscous (also known as pearl couscous) is slightly larger and looks like small pieces of pasta. This kind takes about 10 minutes to cook. The largest kind is Lebanese couscous (also known as Moghrabieh couscous), which is just a little larger and takes about 15 to 20 minutes to cook.
