Roughly chop the cilantro and carefully remove the zest (outer yellow peel from the lemon). The zest adds a lot of flavor to this marinade.
Next, cut the lemon in half and add lemon juice to a mixing bowl. Add the wine, chopped cilantro and lemon zest, followed by the garlic.
Slowly pour the olive oil into the marinade and whisk quickly until it starts to thicken. This is called an emulsion.
When the marinade has thickened, let it sit about 30 minutes and then pour it over your meat.
