How much do you count on your taste buds, as a food writer? Do you use them every day, as a recipe tester, cook, restaurant reviewer, or just because you love to eat?
Then beware of pine nuts. They can ruin your tastebuds for weeks. Actually, they can poison you.
Last Thursday I ate pine nuts at lunch. The next day, a breakfast of fruit, yogurt and granola tasted especially bitter. Lunch was worse. All three dishes I sampled at a hip new neighborhood place were so bitter I could hardly eat them. While making dinner, I was temped to throw out my salmon chowder because of its metallic taste. It tasted like bad white wine. On a hunch, I asked my husband to sample a spoonful. “Really good,” he pronounced.
That’s when I knew something was wrong. Owen Googled “bitter taste in mouth” and found this article about “Pine Mouth Sydrome,” which can last up to a month. It’s a cruel thing to do to anyone in our business who reviews restaurants, or testing or develops recipes, or cooks.
I’m still figuring out what I can eat. I roasted cauliflower Sunday night, looking forward to its caramelized sweetness, but spit out my first taste. Plain green beans were horrible. Cereal and milk goes down fine, but it’s boring. And the metallic taste in my mouth when I wake up makes me think I’ve been eating cars in my sleep.
So if you you love pine nuts, or you want to make pesto this summer, you’re probably wondering whether pine nuts are safe to buy, and from where? Try expensive ones. In the past I’ve paid $28 per pound for pine nuts that looked like the long, slender ones in the photo above. They could have been from Italy or the US.
But buy ‘em cheaply and it’s buyer beware. According to USA Today, Costco has had “a few complaints” about their pine nuts, but couldn’t get to the bottom of it in lab tests. (Here’s more about Costco pine nuts on Chowhound.) I bought mine toasted at Trader Joe’s, where the package said the nuts might have come from Korean, Russia or Vietnam. The pine nuts were tiny, by the way — nothing like the ones in the photo. When I took the opened bag back and complained to a store supervisor, he said the Food and Drug Administration says pine nuts are safe for consumption, while also stating that they “affect one in every 20 people.” That seems like a lot to me. (Coincidentally, guess who else was affected by Trader Joe’s pine nuts? Nicole of Pinch my Salt.)
So, has Pine Mouth Syndrome happened to you or anyone you know? Might you try other nuts instead, from now on? Or are you taking your chances, perhaps with more expensive pine nuts?
