Can you help me with my grammar?

Substitute salsa with sour cream?

@rebbel Ok thanks.

Substitute Sour Cream for the salsa.

@zenvelo Awesome thanks. I wondered if I got reversed.

Both above answers are good but you could be even more clear and say, “ Please substitute an extra sour cream for the salsa.”

“No salsa. Extra sour cream.”

I find this confusing too; I’ve often gotten it reversed. I think I’d go with @Hawaii_Jake and try to be as clear as possible.

Maybe the next time you order, it will be best to tell them that your preferred dip is sour cream instead of Salsa.
