This is an oil flavored with alliums that is great as a garnish for plenty of dishes, but especially ramen.
Add the chopped negi and garlic along with the oil to a sauce pan over medium heat
Once the negi begin to sizzle, adjust the heat to low
Allow the whole mixture to sit at a simmer and continue to sizzle for 15-20 minutes. You want to allow for enough time for the flavors to make their way into the oil but don't want to burn the alliums to a crisp
Remove from the heat and allow the oil to cool
Strain through a fine mesh strainer or cheese cloth and store in an airtight sealed container
