In brief
Ordinary fresh peas are usually removed from the pod. In some types, the pod itself is eaten.
Useful to know
Before preparation, specify what kind of peas you have. Most fresh species are removed from the pods immediately before use. The University of Iowa lists snap peas and sugar peas as edible pod types. [1]
When choosing, it looks for hard, bright green pods without wilting and visible spoilage. Rinse the product under running water before use and refrigerate it as directed. [1]
The practical mistake is to follow one recipe for all types. If the dish is expecting individual grains, a whole hard pod is not an equivalent substitute. If the target is an edible pod vegetable in a fast dish, peeling each pod can remove the required portion.
The source offers peas as an addition to a salad, pasta or dish in a pan. [1] Choose a shape according to the specific product, without assuming that the word "pea" describes everything equally in the package.
