Make the easiest fresh English muffins ever with starter discard - you just need English muffin rings (sometimes called crumpet rings) which you can order from Amazon or King Arthur. I'm sure you can make them from cans too. The key is to have everything ready before you mix the batter ingredients, as you want to use it as soon as ingredients are combined.
When your starter is ready to be fed (even straight out of the fridge for those that keep it there) pull out your discard and put into a bowl. Grease your rings lightly and place them on a lightly greased griddle or skillet. To each cup of starter you have in your bowl, sprinkle over the surface a scant teaspoon of sugar and 1/2 teaspoon each salt and baking soda. Whisk these in thoroughly. Fill the rings with about 1/4 inch of batter and cook it over low heat until the tops are set and full of holes. Remove the rings and flip the muffins over for a minute or two.
After they've finished cooking in the skillet, split them and then pop them in the toaster to brown and crisp. You can also cool them, bag them, and freeze them to bring out and toast later.
