I use Schär Crackers, which are certified gluten-free. For guests with celiac disease, also check the labels on your spices and keep the crackers on a separate board from any bread. The plain ball, without the crust, keeps for up to 2 days in the fridge or 1 month in the freezer; add the crust on the day you serve it. Leftovers keep for 3 days in the fridge. Nutrition is for the cheese ball only, made with ricotta, without crackers.
