Unfortunately, there isn’t a specific recipe to guarantee four red sockets in Path of Exile. However, there are several methods you can use to achieve this, each with its own advantages and disadvantages:
Chromatic Orbs:
This is the most common method, but also the most expensive. Chromatic Orbs randomly change the color of a socket, and you’ll need to keep using them until you hit four red sockets. This can be very resource-intensive, especially for higher-rarity items.
Vorici’s Crafting Bench:
This method involves using Vorici’s "At Least N Colored Sockets" craft in the Syndicate. You can choose to have at least 3 red sockets, which will guarantee at least three red sockets and potentially four. However, this is still not guaranteed and can be expensive depending on the item’s base price and desired number of sockets.
Harvest Crafting:
If you have access to Harvest content, you can use the "Reforge the colour of a non-Red socket on an item, turning it Red" craft. This is a more targeted approach, but it requires specific Harvest encounters and can still be somewhat luck-based.
Combinations:
You can combine these methods for better efficiency. For example, you could use Chromatic Orbs to get three red sockets, then use Vorici’s craft to try and hit four. Alternatively, you could use Harvest to reforge non-red sockets into red, then use Chromatic Orbs to fine-tune the colors.
Additional Tips:
Ultimately, the best method for you will depend on your budget, resources, and desired level of certainty.
