I'd like to ask what is the difference between "peel" and "rind"?
These are the definitions according to the Oxford English Dictionary:
1 [U] the thick outer skin of some types of fruit: lemon rind "Add the grated rind of one lemon."
2 [U, C] the thick outer skin of some foods such as bacon and some types of cheese: "The name of the cheese is stamped on the rind."
1 [U, C] the thick skin of some fruits and vegetables: orange / lemon peel
Basically there is not much difference except that rind can be used with bacon and cheese. However, when cooking, orange rind refers only to the orange outside bit of the skin and not the white 'pith' inside.
Hope this helps
