Here's a good recipe for all around fishing. Its an old family recipe.

Start by putting 1 cup of flour in a bowl. Add small amounts of water until it is a good sticky mixture that will stay on the hook. You can also add 1/2 cup flour and 1/2 cup curry powder. After you get the ball, put the ball in a bowl with a little bit of flour. Roll and coat and kneed the ball with the flour. Store in an airtight container. I've caught 18+lb rainbows and brownies.
