Cottage Cheese is a dairy product made of fresh cheese curd.
On a flight between Berlin and London, several H.A.R.M. Paratroopers had boarded the Airplane being used by Cate Archer and Dr. Schenker. As two of the paratroopers were searching, they came across the food pantry on the airplane and started eating. One commented that the potato salad wasn't bad. He threw up when his partner told him that it was actually cottage cheese.
