In another bowl, combine crushed pineapple, egg, melted butter, milk.
Pour the pineapple mixture with the flour mixture.
Set the batter aside and heat a griddle or non-skillet over medium-high heat ad spray with cooking oil or grease with butter or oil. If you love it thin add more milk.
Scoop about ¼ cup of batter and cook on the griddle, when you notice the bubbles on the edges/top of the batter, flip with a spatula and cook on the other side until lightly brown or to your desired color.
