Definitely A for me.
B here.Um. . .it's been a while since I had corn on the cob; sweet corn season is just beginning. Pretty sure I do B, up and down, but only like 5 rows, then when that part is done I turn it and start on the next 5 rows, so I guess maybe it's a mixture of A and B.
I bought some elote seasoning at Trader Joe's that I'm waiting to try .
