Preheat oven to 200ºC and bake potato gems for 10 mins to soften. Remove from oven.
Spray the bottom of a flat-bottomed glass with a little olive oil and use to smash all the gems. Season with salt and return to oven for another 30 minutes until crispy.
Mix all other ingredients in a large bowl to make the sauce.
Let potato gems cool for 5 minutes so they stay crispier.
Pour all the gems into the sauce and mix.
Serve immediately! This will eventually get soggy so don't wait too long!
