Anthony's Pan-Fried Kitchen prepares two dishes per day. Customers are equally likely to choose either dish. Anthony cooks each dish on a four burner open-flame grill. Anthony's only opens during the week.

Monday: Grilled Salmon or Marinated Goat Tuesday: Calamari Souffl or Sweet & Sour Pork Wednesday: Basil Shrimp or Grilled Salmon Thursday: Duck L'Orange or Calamari Souffl Friday: Fried Chicken or Pad Thai

Anthony uses very fresh ingredients and only uses organic cooking oils, which include vegetable, olive, sunflower, and peanut oils. Right now, the sweet & sour pork, fried chicken, and Pad Thai are cooked using peanut oil, although it is Anthony's least-favorite oil.

Anthony does not use his grill burners in any particular order. His choice to use a particular burner is random. However, burner number three has been experiencing gas-line issues lately which occasionally causes a large flare-up of the open flame. This flare-up only occurs about five percent of the time the burner is in use.

Anthony has three pans he uses for all of his cooking. He does not use the pans in any particular order (they're all the same to him). One of the three pans has an especially loose handle. If the handle came off while Anthony was cooking it is possible that the contents of the pan would spill around the cooking area.

The restaurant's operations manager is very concerned that there is a likelihood of fire. In her risk assessment, she determines that a kitchen fire could occur if cooking oil came in contact with an open flame. All of the burners have splash guards keeping spilled food from an open flame; however, the flame from burner number three spreads around the splash guard each time it experiences a flare-up. This is worrisome because of the loose handle on one of Anthony's pans, although the operations manager thinks there is only about a 10% chance of the pan malfunctioning. Additionally, the only oil with a low-enough flash point to cause a fire is the peanut oil, so she is even less concerned about this possibility.
