Hidden Allergens: Pink Peppercorns, Tree Nut Allergies and how an Amazon Reviewer Helped Solve a Mystery
Pink peppercorns seemed like an innocuous ingredient until they almost killed my daughter. I’m so thankful for an Amazon reviewer for solving the mystery for us.

The information about this hidden allergen is extremely important to share among the nut allergic community and I continually thank the Amazon reviewer who solved a mystery for us.
This post about pink peppercorns could very well save many lives; maybe even the life of someone you know.

My daughter has a severe tree nut allergy,* meaning if she ingests any form of tree nuts, she will stop breathing (anaphylaxis) and die. Even a trace could do the deed–it’s that severe.
Discovering that my daughter was allergic to tree nuts (she was 4)
We learned this the hard way when she was four years old. Denisa ate a chocolate Christmas ornament which was filled with a hazelnut paste. I cannot adequately describe to you what it feels like, and the terror that fills every part of your being when you hear your child barely choke out the words, “I can’t breathe”, and to see her gasping for air.
I immediately called 911, and she was rushed to the hospital in an ambulance. This was my family’s very first experience with any sort of allergy, and it was life-changing for all of us. Nuts were now a dreaded, dangerous and life-threatening food.
The incident at the restaurant
Fast forward 10 years: on the 4th of July, my daughter was at a restaurant at Disneyland with one of her best friends when I received a phone call from her friend’s mother. She told me that she thought my daughter had ingested some form of tree nuts, and was wondering whether to use the EpiPen (a shot of epinephrine) for her anaphylactic reaction.
Of course, I was petrified, and told her that my daughter had to be the one to make that decision.
Luckily, she ended up getting the nuts out of her system and the use of the EpiPen was averted. I’ve since read several news reports that prove that this doesn’t always happen. Sometimes there’s a death, instead of a happy ending. My daughter was incredibly fortunate.

A mystery
At this point, the biggest problem was that the chef was baffled as to how this occurred, as he was certain that the Tortellini Alfredo and focaccia were nut-free. It was the only incident in which we had no idea what had caused her reaction. I spoke to the chef the next day, but there was still no luck in deducing what had instigated her anaphylaxis, so we were left with a mystery.
Mystery solved!
About two weeks after this incident, I was browsing peppercorns and pepper blends on Amazon.com, when I clicked on a Four Seasons Pepper Blend, which included pink peppercorns, or pepper berries. The first review caught my eye:
I couldn’t believe what I was reading, and wondered if the chef might have used this pepper blend in the pasta or focaccia that my daughter had eaten. I quickly did some research, and confirmed what the reviewer had posted. Pink peppercorns were in fact related to cashews!
Immediately, I called the restaurant, and began to ask the chef if he used this pepper blend. I hadn’t even finished asking the question, when he exclaimed, “Yes! Yes! Yes!” What a relief to finally know what had caused her reaction.
It’s disconcerting to think that we actually had a pepperberry tree in the backyard of our previous house, and I used to cut the berries and use them for various crafts. This is what the berries look like.
From Wikipedia:
Peruvian pepper (Schinus molle, also known as American pepper, Peruvian peppertree, escobilla, false pepper, molle del Peru, pepper tree, peppercorn tree, Californian pepper tree, pirul and Peruvian mastic.) is an evergreen tree that grows to 15 meters (50 feet). It is native to rhe Peruvian Andes. The bright pink fruits of Schinus molle are often sold as “pink peppercorns” although S. molle is unrelated to true pepper.
This information needs to be spread as widely as possible:
Pink peppercorns, pink pepperberries, pink berries, Peruvian pepper and whatever else they may be called, are related to CASHEWS and can cause an anaphylactic reaction in those who are allergic to CASHEWS/TREE NUTS.
Here’s what you can do to help spread the word:
- Forward this information to anyone you know who has a nut allergy. I have contacted Penzey’s Spices (who have still done nothing to label the warning 5 years later!) and other spice retailers to ask them to place this warning on their labels. If you can do the same thing, changes will happen more quickly, and hopefully avert potentially life-threatening allergic reactions in future (see update below: great news!)
- If you or your child has a nut allergy, make sure to ask at restaurants, at friends’ homes, and wherever your food is prepared if a pepper blend including pink pepper berries has been used. Inform them that the berries are related to tree nuts.
- Contact newspapers, local TV news, etc. to feature articles or segments on this information.
- Spread the info via social media; ask others to share, re-tweet, re-pin, etc.
- Translate the info into other languages, and share outside our borders.
- Pass on the information by word of mouth; you never know whose life you might save.

My concerns and some points to remember ~
* Many people throw the word “allergy” around loosely. Please be aware of how important it is that this term is used correctly.
It terrifies me that the server who is used to hearing guests order something “on-the-side” due to an “allergy”, notices they ate it anyway. Consequently, they won’t take allergies seriously anymore. Food Babe, who has hundreds and thousands of followers and has written books on the subject of food choices, advises her readers, “Go as far as telling the server you allergic to butter and dairy, soy and corn.”
I, and many others have commented on her post to tell her how this is endangering those who have LIFE-THREATENING allergies which occur within seconds. However, she refuses to remove this wording in her post. In fact, she banned me from her Facebook page when I wrote to tell her the consequences from her advice.
Many people don’t realize that simply touching nuts, and then touching other food is enough to cause anaphylaxis in some allergy sufferers, my daughter included. However, there are others whose allergies are even worse than hers. Think about the nuts being consumed in planes; it’s frightening.
UPDATED 10/19: I flew Norwegian airlines for the first time in June and was horrified at the filthy condition of the floor, including peanuts! I gave them another try this past week and guess what? The same conditions! Do they never clean their planes? This is unacceptable, especially for nut allergy sufferers!

Similarly, there is no barometer to measure or communicate how serious an allergy is. It’s completely open to interpretation. These things directly impact my daughter’s life and so many others’, too.
Finally, please be mindful of the impact that use of the word “allergy” can have.
UPDATE: my daughter attended Villanova University which has a “no nut” policy, which we didn’t discover until after we placed our deposit! I was elated. If you are concerned about your child going off to university with a nut allergy, besides being a top university, Villanova takes allergies extremely seriously. She graduated without an incident at the dining halls and restaurants.

pink peppercorns
My 26 year old daughter developed a tree nut allergy two years ago. Two months after the diagnosis she ate one bite of a peach and had full blown anaphylaxis. It was the first time and since we didn’t know she was allergic to peaches neither she nor I realized what was happening at first. Luckily we used her Epi Pen and got her to hospital but it was horrible. If you are allergic to tree nuts there is a strong chance that you are also allergic to tree fruits, be sure to ask your allergist.
We have since discovered that some places use cashew paste to thicken the sauce in butter chicken. If you eat Indian food, be sure to ask if they use that.
Thanks for passing the word about the pink peppercorns. I have forwarded this to her.
BTW, Allerject is available in Canada, not sure about the US. It is an auto injector that also has voice instructions. It’s also more compact than Epi Pen. Google Allerject to find out more. I have used both EpiPen and Allerject on her and like the Allerject more.
Thank you for sharing! I saw this posted on a Girl Scout FB Group and took notice because my son has a peanut allergy. I mentioned it to my husband, who immediately said “Send me the link, my friend is allergic to cashews.” He forwarded the link, and almost immediately the friend sent a message with a picture of a package of pepper blend from his cupboard that included pink peppercorns with the comment, “I just bought this about a month ago and hadn’t opened it yet. Thank you!”
THIS IS AWESOME!! Thank you so much for sharing the info, Kristin! Both you and your husband probably saved his friend from a nasty reaction, or maybe worse. I hope the news keeps spreading. Thank you for letting me know! CC
I am deathly allergic to chicken cooked and/or processed in either in any way. I can not even be in the kitchen when it’s cooking! I have an Epipen and have become an avid label reader! Thanks for sharing your information.
Wow, that’s pretty severe, LaDonna! Good luck to you, stay safe! CC
I checked the Penzye’s site. So far, all they have is a rather bland statement that pink peppercorns are a member of the cashew family. No “warning” per se. Also, nothing at all in the description of the four peppercorn blend, which also contains the pink peppercorns. Hope they can do better in the future.
THANK YOU for posting this! My 4 year old is allergic to tree nuts (cashews & walnuts specifically) & we carry an EpiPen for him. You are right…it’s terrifying to watch your child go through it. His allergist told us that pistachios are also in the cashew family & that if he reacts to cashews, he will certainly react to pistachios too. Great post. Thanks again!
Thank you for letting me know you got the info, Breegan! I’m so ecstatic to know home many people have learned of this information. I hope your son is one of the lucky ones who outgrow his allergy!CC
I am sorry your daughter had to go through this, thank you for sharing this information it is most helpful. I do however find troubling that you debated the use of the epipen and said that the allergen got out of her body (assuming she threw up – that does not get it out). There was a horrible case last summer in California where there was a wait before using the epipen and it ended in a death of a child. Don’t hesitate, if you think your child is having an anaphylactic reaction or has been exposed to their allergen use it! It can’t hurt, it can only help and save their life.
Thank you, I understand your point of view, but I was not there. I didn’t debate the use of the pen. I hope she ever has anything like this again. CC
Thank you for this info. My oldest daughter is allergic to tree nuts one of which being cashews. We are planning on traveling to Peru in Jan 2015, so this is perfect timing.
So happy you got the information, Heather! Safe travels to all of you! CC
