Why freeze it if you keep it in the fridge for just one week? Depending on what it is, but generally most things last just fine for a week or more in the fridge.
They're probably asking because it depends on the quantity they're making.
I had a friend who asked me if he could freeze the soup recipe I sent him and while confused I told him it shouldn't be an issue.
Later on I'm visiting and he tells me he's making that soup. I walk into the kitchen to see a 40qt/37L pot being cooked. No wonder why he was asking if he could freeze it because the poor fella would have needed to eat 3L of soup a day to finish before it went bad if he didn't freeze it.
