Matzah is made as a whole piece, using a specific recipe.
Tiny chunks of matzah are called matzah farfel or fahfal.
Ground up matzah is matzah meal.
Ground up even further it's cake meal.
They all start out as wheat and water. Avoid them all!

This is exactly the thing that makes me worried when non-informed celiac
