Hi from the Netherlands. We do fries with weird and copious amounts of sauces. Also we do weird snacks.

From our colonialist past we have appropriated peanut based satay sauce. We put that on fries, together with mayonnaise and chopped onions, we call that 'war sauce'.

Also we have a snack that is called the 'bears paw', which is a meat ball, cut into slices and skewered intermittently with sliced onion. This is deep fried and often served with peanut sauce.

So both raw onion and caramelized onion can work with a peanut based sauce.
