Must Know: Ingredients (Walnuts)
Updated: Sep 6
The Essential Difference
Walnuts have a high oil content and a slightly tannic, earthy flavor.
What Is Walnuts?
Walnuts is best understood by looking at its composition, processing and culinary function. Those factors determine how it behaves in pastry, cooking and finishing.
How It Behaves in the Kitchen
They work in cakes, breads, sauces, salads and fillings but can become bitter when old or over-roasted.
Professional Use
Store them carefully because their oils oxidize quickly compared with many other nuts.
Buying and Quality
Choose walnuts with clean aroma, appropriate color and no signs of staleness, moisture damage or off flavors. Buy according to the intended preparation rather than treating every version as interchangeable.
Storage
Protect walnuts from excess heat, humidity, light and strong surrounding odors. Once opened, airtight storage helps preserve its intended flavor and functional qualities.
Common Mistake
A common mistake is using walnuts by habit without considering concentration, moisture, particle size or intensity. Measure carefully, taste and adjust to the final balance.
Chef Tip
Decide what job walnuts must perform—sweetness, aroma, structure, moisture, texture or finishing—and add it at the stage where that function is most effective.
