Thanks for the link, I’ve seen similar articles before. Would like to note I wouldn’t have asked for where I could buy it if I didn’t like it when I actually ate it. I’ve eaten quite a few burgers in my life and I don’t think I need an article to tell me what to like.
That said the bun I’m looking for is a potato bun and not a straight up brioche. I didn’t find that any of the negatives mentioned in the article applied to my eating experience. I like the structure combined with the flavor of potato bun.
The single worst burger delivery vehicle I’ve had is ciabatta (a decision that was made without my input!). Truly terrible lol. Ciabatta in general is just not my thing.
