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
At the age of 63, I still suffer the same severe consequences when ingesting tree nuts – NOT peanuts, NOT pine nuts – TREE nuts. Always thinking I’m one step ahead of the ER or Epipen, I always ask about food prep in restaurants when I see a tree nut dessert on the menu (nuts chopped on a wooden board and then the veal pounded on the same one? trust me, I had a reaction to that one!). At potlucks I’m the one always asking what’s in the dish (in the nicest way possible, of course). So when a Penzey’s finally opened here in ATL, I was beyond excited! The first thing I did was taste a few blends and then spotted pink peppercorns. We love to cook, so I popped one in my mouth in order to decide how I would love to incorporate them into recipes and we continued our culinary tour. For the life of me (no pun intended) I couldn’t figure out why the itchy mouth and swollen lip. NOW I KNOW!!! Holy cow! And I cook – a lot – my daughter is a chef who preaches the gospel about tree nut allergies and the difference between that and peanuts (legumes) to everyone in the kitchen(s). But pink peppercorns? Thank you, thank you for sharing this. I can assure you we will do the same far and wide. BTW, the one peppercorn ingestion fortunately didn’t cause anything but discomfort, but don’t get me started on hazelnuts…!
Wow, Becky! That’s unbelievable! SO glad your pink peppercorn incident didn’t cause a full anaphylactic reaction! I’m very happy that you found my post and now know why you reacted to the peppercorn in the first place. Yes, I also know that hazelnuts are the original problem that my daughter had, so we really fear those the most! Good luck to you and please spread the word! CC
I definitely will be passing this on. I don’t personally have nut allergies in my family, we have shell fish and wheat. Which can be just as deadly. This information could and will help save anyone going thru a reaction is worth the time it takes to post and forward. Thank You so very much Christina .
I really appreciate your message, Melody! You are 100% correct, that this information would definitely save someone from a reaction and possibly even death. Thank you for passing on the info, and good luck with your allergies, too! CC
Thank you so much for this information! I was travelling in Germany two summers ago when I had a severe allergic reaction to the pepper that I put on my meal. It was not regular black pepper. Now I know why!!
So glad you figured out the mystery, too, Amanda! Thanks for letting me know! CC
Are “pink peppercorns” listed that way on the labels or does the ingredient “pepper” include this?
Thanks so much for this information!!
Margaret, that’s a very good question. I don’t know because each company can label things differently. I would call the company in question and ask them directly. Good luck and you are very welcome! CC
Thank you so much for sharing. My grandson has a severe tree nut allergy and this is something we did not know about. It is so difficult to eat out because unless someone has a nut allergy or has a loved one with a nut allergy, I really don’t think they take it seriously. When asking a chef, they are usually very helpful but the added seasonings, I am not sure they consider as having something that could be harmful to the person allergic. Thanks again and I will spread the word.
I completely understand, Kathy, but it is SO refreshing when someone does understand and goes out of their way to make sure the meal is truly nut-free. I was going to be in Europe when my daughter went to winter formal last December, so I spoke to the chef at the hotel where the dance was being held, beforehand. He went as far as making her her own meal and let her choose what she wanted, her table also was given a selection of nut-free desserts! I couldn’t believe he took so much time for one guest, but was so relieved to know she was in good hands when I was so far away.
Do make sure to ask in restaurants if they use this 4 blend pepper as I’m sure no one considers it a nut-allergen. Good luck and thank you for sharing the information! CC
Thank you so much for sharing this information. My son is allergic to tree nuts and especially to cashews. I’ve let him know and will spread the word.
So glad you found this information and are passing it on to your son!! Thank you! CC
Thank you so much for this important information. My 4 year old is very allergic to tree nuts, we also found the allergy when he ate a Christmas treat. Thank you again for spreading the information, I will be sending this along to everyone I know.
Sorry to hear your son is in the same boat as my daughter, but I am so happy that your got this information! Thank you for sharing it with others! CC
We quickly learned that there is a small amount of pine nuts used on focaccia while on a cruise last year. It was such a small amount, the chef didn’t even know about it. Luckily, the epipen wasn’t needed.
Hi Brittany, yes, my daughter is also allergic to pine nuts, even though they are not considered tree nuts. I’m glad whoever was allergic was fine as that would be super scary to have an anaphylactic reaction on a cruise! Good luck, CC
