Frying Time and Temperature Chart

The Oster CKSTDFZM70 manual includes a cooking chart with recommended temperatures and frying times.

The recommended preheating time is 7–10 minutes. Cooking times may vary according to the amount and thickness of the food.

Prepackaged frozen cooked chicken may require less cooking time than uncooked chicken.

Tips for Better Deep Frying Results

Correct food preparation, oil selection, and frying temperature help produce properly cooked food.

Avoid Overloading the Basket

Food must be surrounded by cooking oil to fry correctly.

Too much food causes the oil temperature to drop, resulting in food that may become soggy or greasy.

The food level must remain below the top edge of the basket.

Remove Water and Ice from Food

Food must be thoroughly dried before frying.

Ice crystals should be removed from frozen food before it is lowered into the oil.

Excess water and ice can cause hot oil to splatter or overflow.

The manufacturer recommends allowing frozen foods to defrost for approximately 20 minutes before frying for improved crispness.

Use Battered or Breaded Foods

Foods coated with breadcrumbs or batter are suitable for deep frying.

The coating forms a protective layer that helps retain moisture inside the food while allowing the outside to become crisp.

Shake the Basket During Cooking

For more even cooking, the frying basket should be shaken halfway through the cooking time.

The lid must remain closed when food is immersed in or draining above hot oil.

Select the Correct Temperature

Using the recommended frying temperature helps produce evenly cooked food with consistent browning.

Oil temperatures that are too low can contribute to greasy food, while incorrect temperature selection can affect the cooking result.

Recommended Cooking Oils

The manufacturer recommends cooking oils with higher smoke points.

Suitable oils identified in the manual include:

• Blended vegetable oil
• Pure corn oil
• Sunflower oil
• Soybean oil
• Grape seed oil
• Canola oil

The manual advises against using seasoned or flavored oils with lower smoke points, including walnut oil, olive oil, lard, and drippings.

Peanut oil is also discouraged because it can significantly affect the flavor of fried food.

Do Not Mix Cooking Oils

Different cooking oils must not be mixed during deep frying.

High temperatures, water, and burned food particles can lower the oil’s smoke point and reduce its frying effectiveness.

Cooking Oil Maintenance and Storage

Cooking oil deteriorates with repeated heating, moisture exposure, and food residue.

Oil condition must be checked before reuse.

When to Replace Cooking Oil

The oil should be replaced if any of the following conditions appear:

Cooking oil may become darker and thicker after repeated use.

The manufacturer explains that oil changes occur because oil and food molecules are exposed to prolonged high temperatures.

Oil Use After Frying Chicken or Fish

The manufacturer recommends using oil only once when cooking foods with strong flavors or aromas, such as fish and chicken.

Repeatedly using such oil can affect later frying results.

Filtering Used Oil

Cooking oil may be filtered using a cooking oil filter or a fine-mesh strainer.

Filtering removes food particles and can help the oil remain suitable for further use.

Oil that already shows signs of deterioration must be discarded rather than reused.

How to Store Cooking Oil

1. Allow the cooking oil to cool.
2. Filter it when appropriate.
3. Transfer it into an airtight container.
4. Keep the covered oil in a cool, dark location.
5. Store it for no longer than the recommended period of up to three months.
6. Check the oil’s color, smell, and tendency to foam before using it again.

The manufacturer instructs against refrigerating cooking oil.

Chilling the oil and then returning it to room temperature can result in excessive splattering during the next heating cycle.
