What you need to do for the tradition is to talk to the sims in Finchwick. Mostly it's the owners of the vendor stalls and the bar plus the Mayor and Grocery Deliverer. There is an option to have a heart to heart talk with them. They will tell you things like what another Finchwick sim likes. You might have to do it several times as you also get a lot of the history of Henford on Bagley so just keep trying. Then you find the thing mentioned for a certain sim and put it in your inventory. Then go find the sim who likes it and you should get an option to give them a favor so you give or gift it to them. It might take a while sometimes. Some are easier than others as you might have to have certain ingredients or go find something.
Hope this helps.
