Combine all dip ingredients in a medium bowl and stir to combine well. Refrigerate while you make the steak fries.
Set oven to 425ºF/220ºC
Scrub potatoes well but don’t peel (unless you really, truly desire). Cut each potato lengthwise into 12 wedges: Half, then cut-side-down cut each into half again, then carefully cut each half into three wedges. See video demo.)
Put the oil in a large bowl and add potato wedges, using your hands to fully coat each wedge. Then add the seasonings and mix again.
Arrange on a baking sheet in a single layer.
Bake for 20 minutes, then remove from oven and turn. Bake another 10 minutes until steak fries are tender and roasted outside.
