You gain mastery over two recipes and can craft them with little effort. Choose two potions, elixirs, or bombs that you have learned and who's Risk DC is equal to or lower than your Intelligence ability score. These become your signature recipies. You always have these items prepared, they don't count against the number of items you have crafted, and you can craft each of them three times per day without expending ingredients or essences, without making an Alchemy Check, and as a free action. When you do so, you can't do so again until you finish a short or long rest.
