Is saskatoon berry high in sulfites?

Watch for

• It is a pome in the apple tribe, alongside pear, quince and hawthorn, rather than a relative of the blueberry.If raw apple or pear gives you an itchy mouth or throat from birch pollen food allergy syndrome, that botanical relationship is a reason to take a small first taste and wait. There is no cross-reactivity data specific to saskatoon, so this is a relationship worth knowing rather than a tested finding
• The almond note is the seed, not a flavouring.Saskatoon seeds are soft enough to eat and they are what give cooked saskatoon its marzipan character. At eating quantities this is a flavour fact rather than a hazard, but it is the reason the fruit tastes nothing like the blueberry it resembles and the reason recipes lean into almond extract
• FODMAP grades are unrated rather than low.Saskatoons are eaten by the handful off the bush and baked by the litre in the prairies, and those are very different exposures with no published portion figure behind either
• Mild salicylate and mild histamine liberator grades, both well under blueberry, which grades high for salicylates.That gap is what makes saskatoon a workable stand-in when a recipe calls for blueberry and blueberry has been a problem
• Nearly all commercial saskatoon arrives frozen, or as pie filling, syrup, jam or sweetened dried fruit.The dried form in particular is usually infused with sugar or juice concentrate, which is a different food from the fruit these grades describe
