How would you say "pancake batter?"
How would you say "Pancake batter," or just "batter" in general (such as the food batter).
The word "mezcla" is commonly used for cake batter, so I presume it can also be used for pancake batter. In Mexico "pancakes" are called "hotcakes", so you could say "mezcla para hotcakes".
"Masa" is also used to refer to a mixture of ingredients that needs to be baked, but that seems to refer more to the English word "dough".
