In Winnipeg, we have a variety of rye bread that is white, light, and fluffy. In the rest of Canada, it is sold as "Winnipeg-style Rye", but in Winnipeg it's just "Rye". It's seriously the best.
For jam, we've got a single grape plant in the backyard that produces about 15L of grape jelly every year. An insane amount for a single plant. Not 100% sure on its variety (maybe Valiant) since it was already 30 years old when we bought the house. But fucking awesome.
For peanut butter, we actually tend to use "Nature's Nuts Nut and Seed Butter" -- which is some mix of: almonds, cashews, chia seeds, hazelnuts, sunflower seeds, pumpkin seeds, and Brazil nuts. Made in Canada, but obviously a bunch of these things don't grow in our climate ;)
Edit: just realized this conversation is on lemm.ee which is shutting down. Sadness. Looks like a similar community will spin back up on lemmy.world
I'm not crying! You're crying!
