"Kiwis cause milk to curdle..."

was the title of an e-mail Adam sent me last week. He went on to say, "Unfortunately found this out with my breakfast cereal. :( " and referenced this "Note: Raw kiwi contains an enzyme that prevents gelatin from setting and causes milk to curdle." from this website. Curdled cereal milk sounds pretty nasty and I can also attest to the little fact about gelatin, I remember my fruit terrine failing to set years back because I'd added kiwi to the mix.
