Is there a generally accepted best way to experiment with recipes?
When starting with a recipe that is not 'quite right', if you wanted to tweak the quantities of various ingredients (and taste the results), what would be the most efficient or 'correct' way to go about this? I am asking in the context of baking where it is hard to know how something will turn out until it is finished.
Is it best to do one batch at a time, taking notes of how the result turned out and then tweaking next time around, but having to go through many batches before figuring out the best recipe? Or, is it generally better to make several mini-batches at once, and taste them side by side?
Is there an accepted standard for how to implement this experimentation process?
