I don't know if this has been done as a Topic. I don't have a huge amount of experience with these types of products, and thought I'd see what others' preferences are. (I'm also thinking this is a topic where Toliver might have had something to say. RIP, Tim.)
The products I can recall having are Ore-Ida fries, crinkle fries, tater tots, and crowns, Alexia onion rings, sweet potato fries and sweet potato puffs, Kroger sweet potato crinkle fries, Safeway Signature Select onion rings, and Checkers/Rally's fries. I've probably had others that have slipped my mind.
I like Checkers fries. Those are what I've been buying lately. The Ore-Ida items I've had are okay but are something I'm likely to buy only rarely.
I also like Alexia onion rings. I do not like the Safeway onion rings (minced and formed onion.) i'm sure I've had other brands of onion rings, but they must not have made enough of an impression good or bad for me to remember them.
As I recall, Alexia sweet potato fries and puffs are decent. Alexia seems to be a pretty good brand. I need to try more of their products. Kroger sweet potato crinkle fries are okay.
I have some Arby's curly fries in the freezer at the moment, but since I'm not a big fan of Arby's curly fries I'm not expecting much from the frozen variety.
Anyone have any favorites?
