Harissa is a spicy paste that people use to add flavor to their food. It comes from North Africa, which is a place far away on the other side of the world.
To make harissa, people mix together different spices, like chili pepper, coriander, and cumin. They also sometimes add ingredients like garlic and lemon juice. Then, they grind everything together until it becomes a paste.
When you eat harissa, it makes your mouth feel spicy and warm. Some people like to put it on their sandwiches or mix it into their soup. It can also be used as a condiment for meat or vegetables.
Just remember, harissa is spicy, so if you try it, make sure to start with a little bit and see how you like it!
