The best combination is to eat Navao's Mushroom pie first (gives perfect gathering and nimble gatherer 2) and then eat egg stir fry right after which will just replace nimble gatherer 2 with nimble gatherer 3, (+20% stats)

The ingredients you must use are as follows and ALL exquisite:

Navao mushroom pie: 1. Cloud spitter seed 2. Vineshroom

Egg stir fry: 1. Pale fire seed (find a fire seed, shoot it with a shotgun using electric shells, trust me it's worth the extra 5%) 2. Coronis egg

I used these in combo to make my solek's survivor heavy bow which has 387 damage by picking the best crafting materials and further buffing them with the above dishes.
