In terms of shells, walnuts tend to rest in the comfort of a light brown, round, dense, ridged shell. Pecan shells, on the other hand, tend to be darker, more oblong, and more difficult to break open. For the edible portion, walnuts are a bit light and larger to their pecan counterpart, with a convoluted, “brain-like” shape. Pecans, on the other hand, are typically found in their halved form.
These pecan halves are smaller than walnuts, a brighter and warmer brown, and are typically straight in appearance with one distinct, central fissure. Understanding the differences in appearance and texture can help us to superficially understand the differences in their uses in the culinary world.
Walnuts tend to be a bit bitter compared to other nuts and are used to add a crunchy texture in desserts, salads, granola’s, and oatmeal, among others. Pecans hold a more distinct flavor profile and contain a slightly sweeter taste. They therefore add a whole new element to several recipes and can be found in sweet potato casseroles, sweeter salads, pastries, and pecan-centric desserts.
In terms of purchasing value, walnuts tend to be a bit more expensive but have a longer shelf-life when stacked up next to pecans. Overall, walnuts and pecans can typically be swapped in most recipes, however, there are some key differences between the two to be aware before deciding to include them in your meal plan.
