喷香

Note the tone: it's pèn (4th tone) here, not pēn - 喷 changes meaning depending on tone. 喷香 is mostly used predicatively or attributively for food and cooking smells: 喷香的米饭 (deliciously fragrant rice), 香喷喷 (same meaning, reduplicated form). Slightly informal/folksy register, common in spoken Chinese and food writing.

memory

喷 (to spurt / spray) + 香 (fragrant) = a fragrance so strong it 'sprays out' at you. Picture steam billowing out of a hotpot - that explosion of aroma is 喷香.
