For the tortilla chips: Preheat the oven to 350 degrees F. Brush the tortillas with the oil on both sides and season one side with salt, pepper and cumin. Place on a baking sheet and bake until lightly golden brown, about 10 minutes. When cool enough to handle, cut into eighths or break into chip-size pieces.

For the guacamole: Combine the avocados, corn, jalapeno, onions, cilantro, lime juice and creme fraiche in a bowl and mix well. Season with salt and pepper. Serve with the cumin scented tortilla chips.
