Injera is a type of bread that comes from Ethiopia. It's made from a special grain called teff which is ground up into a flour.
To make injera, you mix teff flour with water and let it sit for a while so it can ferment. Ferment means it gets bubbly and fizzy.
Then, you pour a little bit of the batter onto a special hot plate called a 'mitad'. The batter will spread out and cook until it's ready to eat.
Injera is a bit sour and spongy, and people in Ethiopia use it to scoop up different kinds of stews and sauces. You might find it at an Ethiopian restaurant, and it's a really popular food in that country!
