I’m not sure how or why grape became the default. For the longest time, I thought I didn’t like PB&J. But ever since trying it with strawberry instead, I understood the appeal. It’s so much better, and now I find it weird that the combination isn’t more common.
Grape is a default in the US for historical reasons, that’s what was in the WWII ration packs, and inertia carried it from there.
Generally. I hear so much about grape flavoured this and grape flavoured that from US-based media. Anything that goes beyond grape juice is a rarity here in Germany. A lot of what would be grape flavoured in the US is black currant flavoured here.
My goto jam for pbnj is apricot though. Can highly recommend.
Holy crap German jam aisles were delightful when I was last there! There are SO many interesting flavours, all PACKED with actual fruit and seeds ❤️
