Heat a medium saucepan over medium-high heat. Add onions, garlic, ginger, celery, and carrot; cook until well browned, about 8 minutes. Add the stock, scrapping any browned bits from the bottom of the pan. Add the bay leaf and bring stock to a boil, then reduce to a simmer and allow stock to gain the flavors from the aromatics, 30 minutes to an hour.
In a small bowl, make a slurry of the cornstarch and the water. Set aside.
Pile the hot fries onto a serving plate and sprinkle fries with cheese curds. Pour warm gravy over the fries making sure to leave parts of the fries exposed to ensure crispiness, and serve.
