IPA: /ˈrʌsɪtɪŋ/
KK: /ˈrəsɪt/
A brownish rough area on the skin of fruit, like apples, that happens due to damage.
The apples had russeting, making them look rough and brown in some spots.
Russeting is derived from "russet" (from Old French *russet*, meaning reddish-brown) and the suffix "-ing" (indicating a process or action). The term refers to the process of developing a reddish-brown color, particularly in fruits like apples.
Think of the word 'russet' which means reddish-brown, and remember that 'russeting' describes the process of something turning that color.
