Bake the fries according to package directions. While the fries are cooking, chop the cilantro and prepare the garlic mayo.
To make the garlic mayo, place the mayo, milk, and garlic powder in a bowl and stir to combine. Pour the garlic mayo into one of these to make it easier to drizzle.
When the fries are done, season with a pinch of salt if desired. Pile them on a long oval or rectangular plate. Drizzle with hoisin, sriracha, and garlic mayo. Start with 2 teaspoons of sriracha and adjust to preference. Top with crushed peanuts and chopped cilantro. Serve warm.
