How to unlock the Master Chef achievement in Niffelheim - Definitive Guide
-During the day, go around each of the 4 territory maps holding down the "A" button and you will automatically harvest things that can be used to cook. Additionally kill the different animals during the day to use their meat as a cooking ingredient.
-You can then cook using the Kitchen on the right side of your workshop. Higher levels of kitchen allow more cooking recipes.
-I am unsure if using the Kitchen Pot on the right side of the map counts or not.
This trophy may not happen naturally, depending on if you're cooking your own food or purchasing items from the store in Temple City. If you decide to purchase most of your food, don't worry, this trophy won't be too terrible a grind to get.
As you adventure around collecting vegetables, plants, mushrooms etc., you'll also pick up "Dry Seeds". These drop off most plant-related items so you'll be racking up a pretty good number as you go along. These will be used to make the easiest (and least expensive material wise) item: Flour.
You'll need Kitchen Workshop stage 2 for this (you'll be getting to stage 5 anyway for Great Architect and Handyman!). Once you have unlocked stage 2, you'll be able to make all the flour you can handle. One bag requires 2 Dry Seeds to make and, again, you'll be picking up a lot of these. If you don't have this trophy by the time you've reached 100 days, keep making as much flour as you can and you'll be able to get this trophy done in no time.
After you crafted your 100th food item in the Kitchen Workshop, the trophy will unlock.
