Junksmith: Achievement PSN of South Park: The Fractured But Whole

Over the course of the game you will find tons of recipes as loot and they can be bought at most shops. There are way more than 10 recipes in the game. Buying cheap recipes from shops (e.g. Freeman's Tacos) is the fastest way.
Now you need to craft those recipes. You have to craft 10 different ones, it cannot be the same one 10 times. There are plenty of crafting materials found as loot around the map (from containers etc).
It's best not to bother with this until after the game. By then you'll have enough recipes and crafting materials to do this. Some crafting materials can also be bought from shops.
