Q4A pastry chef changes tools and washes hands after handling raw eggs and before decorating cupcakes with whipped cream. What potential issue is the chef most likely avoiding by taking these actions?
Show answer
✓ Correct answer: Cross-contamination
The correct answer is cross-contamination. Cross-contamination is when harmful bacteria are transferred from one substance or object to food, which can occur when handling raw eggs without proper hygiene measures. Washing hands and changing tools between tasks can prevent bacteria from transferring to other food items, such as whipped cream. Allergic reactions are typically caused by exposure to allergens, which is not necessarily prevented by handwashing and changing tools. Color bleeding and flavor mixing are not related to cross-contamination caused by handling raw eggs.
Q5A restaurant has set a par level for chocolate chips at 10 lbs. They currently have 5 lbs on hand, use approximately 10 lbs per week, and maintain a safety stock of 2 lbs. If the delivery lead time is 2 days, how many pounds of chocolate chips should they order to meet their par level?
Show answer
✓ Correct answer: 5 lbs
Answer: 5 lbs Using the par stock method, the restaurant brings their inventory up to the par level each time an order is placed, regardless of current inventory levels. In this case, 10 (par level) - 5 (amount on hand) = 5 (order). The other options are calculated using incorrect inventory methods that would consider additional variables, not strictly par stock method.
