Preheat the oven and cook fries according to instructions on the bag.
While the fries are cooking, measure out creme fraiche and add the juice from 1/2 of a lemon. Mix together well with a fork. Set aside.
Once fries are cooked, move them to your serving plate. Drizzle with lemon creme fraiche, then distribute pods of caviar across the fries. Top with chives and serve immediately.
