How do the physical characteristics and composition of Sugar Snap Peas differ from Snow Peas, especially concerning pod structure?

Sugar Snap Peas have plump, rounded pods containing larger, sweeter peas.

The distinction between these two edible-podded legumes lies primarily in their maturity and structure. Snow peas are characterized by their flat pods because the peas inside are very small and underdeveloped; consequently, snow peas tend to be leaner in terms of overall calories and carbohydrates, as they consist largely of pod structure and water content. In contrast, sugar snap peas are cultivated to have fully developed, plump, and rounded pods, which house significantly larger and sweeter peas. This results in sugar snap peas containing higher levels of starch and natural sugars compared to their snow pea counterparts, offering a different textural experience and slightly different macronutrient density per serving.
