Rashi on Genesis 27:27/רש"י על בראשית כ״ז:כ״ז

1’וירח וגו AND HE SMELLED etc.— Surely there is no more offensive smell than that of washed goat-skins! But Scripture implicitly tells us that the perfume of the Garden of Eden entered the room with him (Genesis Rabbah 65:22).

2כריח שדה אשר ברכו AS THE ODOUR OF A FIELD WHICH THE ETERNAL HATH BLESSED — to which God has given a pleasant perfume: it refers to a field of apple-trees. So have our Rabbis, of blessed memory, explained it (Taanit 29b).
