Katmi are traditional Bulgarian pancakes, similar to crepes but thicker and with a slightly spongy texture. The batter is made from flour, milk (or water), eggs, yeast or baking soda, and a pinch of salt, with some recipes including yogurt for added tang and texture.
The batter is mixed to a smooth, pourable consistency and allowed to rest, especially when yeast is used, to let it rise slightly. Katmi are cooked on a special griddle or pan called a "sach" or a regular non-stick pan over medium heat. Unlike crepes, they are thicker, with a surface full of small bubbles or holes, giving them a spongy texture that helps absorb fillings or toppings.
Traditionally, katmi were spread with just butter, lard, or oil. Today, however, they can be served with a variety of sweet toppings like honey, jam, or chocolate spread or savory ones like cheese, butter, or minced meat. Katmi are often rolled or folded and served warm.
