Questions & Answers

Q: What is vacuum frying and why is it necessary for frying fruits and vegetables?

Vacuum frying is a technique that lowers the pressure in the pot, changing the boiling point of water and allowing for frying fruits and vegetables at lower temperatures. This is necessary because the high water content in fruits and vegetables would cause scorching at high temperatures.

Q: How do vacuum fried bananas differ from normal fried bananas in terms of texture?

Vacuum fried bananas have a crispy outside and a moist interior, while normal fried bananas have a thin skin and a soft texture. The difference in texture is due to the lower cooking temperature used in vacuum frying.

Q: What is the advantage of vacuum frying in terms of flavor preservation?

Vacuum frying allows for frying fruits and vegetables without cooking them excessively, preserving their natural flavor. The lower cooking temperature prevents the food from losing its flavor and becoming overly browned.

Q: What setup is required for vacuum frying at home?

A setup for vacuum frying at home typically requires a stainless steel pressure cooker with modified fittings, a vacuum pump, and a cold trap to collect the water removed from the food during frying.

Summary & Key Takeaways

• Traditional deep fat frying removes water from food and replaces it with hot oil, but frying fruits and vegetables poses a challenge due to their high water content.

• Vacuum frying lowers the pressure in the pot, changing the boiling point of water and allowing for frying fruits and vegetables at lower temperatures.

• Vacuum fried bananas have a crispy outside and a moist interior, while normal fried bananas have a thin skin and a soft texture. Pressure fried bananas are extremely crisp on the outside and soft on the inside.
