The sweetness of a pea is more than just a desirable taste; it’s an indication of a pea picked at the perfect moment. As the sugars convert into starch, peas lose their sweetness rapidly after picking, leading to a less sweet, more fibrous and lower-quality product.
That’s why high-quality peas are picked, blanched and frozen as quickly as possible, usually all within two and a half hours. That said, other factors such as soil, seed quality, transportation and a stable freezer temperature all affect a frozen pea’s quality.
