Modded Minecraft can be quite overwhelming to someone who is new to it. Recipe Discovery attempts to ease this by showing what exists, but hiding recipes behind unlocks. As a player collects items it'll then notify them of any recipes they unlocked. The mod currently supports the vanilla recipe book and EMI with plans to support JEI soon.
When a recipe is unlocked the output of it will be highlighted with a star so you can keep track of recent unlocks and general progression. Recipes are unlocked by picking up all the ingredients that go into it. The highlight will go away once you click the item.
Theres also an enhanced discovery toast to tell you how many recipes you unlocked.
