Heat the oven to 350°F, place the butter in a 9-by-13-inch dish and melt it in the oven for 5 minutes.

Whisk the self-rising flour, sugar and milk into a mostly smooth batter.

Pour the batter over the butter without stirring, then distribute the cherries and reserved liquid across the batter without stirring.

Bake for 45 to 50 minutes until the crust is browned and cherry filling bubbles through it.

Rest 30 minutes before serving.
