Atticus truly hits the Southern culinary jackpot after his defense of Tom Robinson in To Kill a Mockingbird. The African-American populace of Maycomb is so grateful to Atticus for his staunch defense of Tom that they send him a load of fresh-cooked delicacies. Tom's father sends Atticus a chicken, to which Atticus states that he bets "they don't have chicken for breakfast at the White House." Atticus also receives fresh baked rolls from "Estelle down at the hotel... The kitchen table was loaded down with enough food to bury the family." The gifts included salt pork, tomatoes, beans, scuppernong grapes, and Atticus' favorite: pickled pig's knuckles.

I think that what you are asking about can be found in Chapter 22.

In this chapter, the trial of Tom Robinson is over.  Tom has been convicted of raping Mayella Ewell.  Even so, the black community in Maycomb is really grateful to Atticus for defending Tom.  So they have sent him stuff.

Tom Robinson's father has sent a chicken.  Estelle from the hotel has sent rolls.  A lot of other stuff has been sent as well.  Calpurnia says that most of the other stuff was left on the back porch and was there when she got there that morning.

The kitchen table was loaded with enough food to
bury the family: hunks of salt pork, tomatoes, beans, even
scuppernongs. Atticus grinned when he found a jar of pickled pigs'
knuckles.
