Need one more ingredient for the festival

[N7Mitch]

I need vinegar to complete Franklin's order of Mushroom Salad. Anyone got this item?

 

[Isabelle for president!]

Just visit your villagers in their houses, they'll ask for fish and they'll trade with you for vinegar, milk, butter, sugar, flour, mushrooms and fruits.

I'd love to help, but I already finished festival and don't have any to share.

 

[Hostile Kangaroo]

I have an extra vinegar that I got looking for flour. If you have flour I'd love to trade.
