Combine 2/3 cup breadcrumbs with other ingredients for sticks in a food processor and pulse a few times until roughly chopped.
Form into stick shapes, dip into remaining crumbs, and turn to coat all sides.
Heat about 1/4-inch of oil in a medium skillet over medium heat. Fry a few sticks at a time for 1-2 minutes per side, then transfer to a paper towel-lined plate.
To Make the Crema:
Combine all ingredients in a food processor or blender and pulse until smooth.
Pour into a small saucepan and place over medium-low heat.
Stir constantly until it begins to thicken, about four minutes.
Serve warm with sticks or refrigerate to serve cold.
Notes
If you prefer, these can be baked at 400°F for 12-15 minutes until crispy instead of frying.
