Pros: Blue Apron, founded in 2012, was one of the companies that started the subscription food-box boom, and is pretty much the gold standard of food delivery services. It's the most profitable, popular, and probably the most well-known, making it a solid start for mail-order-food virgins. The ingredients are meticulously packed and the seasonal menu is idiosyncratic. I like it because -- like most of these services -- it gives me the option to experiment with food I wouldn't think to make on my own, and access to ingredients and dishes I would probably never encounter organically, like "spicy Korean rice cakes with broccoli, tofu, and cashews," or "pork burgers with pickled beets and cone cabbage slaw." It also allows you to experiment with new tastes without buying a full bottle of some random spice or garnish (fennel pollen?).
Also, the portions are VERY generous, so unless you are feeding a family of eight competitive eaters, expect leftovers. Overall, the food is of a high quality, and the offerings -- especially within a given week -- are diverse enough to never feel stale.
Cons: If you are super-waste-conscious, BA's incessant packaging (it literally will individually wrap pickles) might kill your eco-friendly soul. Also, some of the recipes can be a little complicated -- and almost always take more time than what's laid out on the recipe cards. And like I said in the pros, you'll get a mound of leftovers, which some people might see as a con.
Rating: 9/10. Great first option to try out to see if the sub-box thing overall is a good choice for you, and maybe the best choice, overall.
