Ingredient field notes / fat
Cooking oil: refined canola
A mild liquid fat that coats ingredients and can be dispersed into droplets in a dressing.
Preparation changes the job.
Record the oil type and any flavoring shown on its label. Refined and unrefined oils should not be assumed to behave identically during cooking. Follow the oil label and recipe for heated uses rather than choosing a temperature from this profile.
Look a little closer
In a closed observation container with water, look for separate layers and for smaller droplets after mixing. Oil’s failure to dissolve and its position in the container are different questions: molecular interactions influence mixing, while density influences which layer lies above the other.
Put it to work
Use the oil called for in a dressing recipe. Whisking or shaking breaks it into droplets; a mixture can look combined at first and later separate. Describe the appearance at a stated observation time.
Supply a dressing’s fat phase
The oil becomes droplets within the water-containing ingredients when a suitable dressing is mixed.
Coat and carry flavor
A measured amount coats ingredients in a dip or sauce and carries some fat-soluble flavor compounds.
Go deeper
An emulsion contains droplets of one liquid dispersed through another. Mixing creates droplets, while suitable emulsifying ingredients can help them resist joining together. Using more force does not make oil become a water-soluble substance.
