Put the ginger, garlic, mint, lime juice, salt, and pepper in a bowl or a jar with a lid.
Add the lime juice, and the olive oil, and whisk or shake to combine well.
Notes
Once a marinade touches raw meat or seafood, it has to be either boiled or discarded. But what I sometimes do is take a few tablespoons of the marinade out before I put the meat in (make sure to give it a good shake, whatever it is, so that the marinade is completely combined before you pull some to the side).Then, after I cook the chicken or chops or whatever, I dribble the reserved marinade on the cutting board before putting the cooked food back on to rest and then slicing. Extra fresh flavor at the end.
