We've never bothered blanching our peas and they always come out fine. But all our beans get blanched, mostly to extend the freezer life and texture. I'd be sure to eat the non-blanched items first. Broad beans just need a quick blanch, not even a minute as it needs only 3 minutes for larger beans to cook for the table. I'm not a fan of frozen carrots myself, but I'd blanch them first.
