Someone else mentioned pawpaws but i just want to emphasize pawpaws are the shit. Plus if you live in the Eastern US especially the Midwest pawpaw season is HERE. You have no excuse not to leave your house this moment and find your nearest pawpaw grove.
Not convinced? Congrats you have subscribed to pawpaw facts:
they are related to the custard apple and were brought this far north in the shit of prehistoric giant sloths
they taste like somewhere between a mango and a banana, and so our ancestors in all their wisdom gave them names like Indiana banana, Ohio banana, \ banana
they are a CAPITALIST NIGHTMARE as they have terrible shelf life so can really only be eaten fresh or bought from a farmers market
foraging for pawpaws is super fun as they grow in groves, have super skinny trunks and branches with large long leaves and surprisingly big fruit. To harvest pawpaws you give the trees a gentle shake and ripe fruit will just fall off. Don’t shake too hard or you might knock down fruit that isn’t ripe! Not cool!
to enjoy just shake em down, cut it open and eat the fresh fruit inside (not the skin). Do not eat the big ass seeds leave them where you found em so that out beautiful native pawpaw groves FLOURISH
All in all pawpaws are 10/10 if you want to feel like a literal Animal Crossing character shaking down trees for sustenance and having a great time eating fresh fruit outdoors
Concord grapes. You all know the flavor, because it’s the flavor that artificial grape flavor is based on, but I’ve only seen the real things in farmers’ markets in the Northeast US. They’re only available for a short period, and they’re amazing. A blend of intensely sweet and intensely tart.
While sugar beet is hardly unknown, try Zuckerrübensirup if you're near Germany, a black-ish sirup made from them. You can usually also get it in the Netherlands and sometimes in Denmark at least.
There are similar products in other countries, but they lack the distinct taste the German variant has that makes it such an awesome spread! And no, it has nothing to do with Marmite, which is a good thing.
Mulberries are awesome; they're tasty and they're an excellent source of dietary iron, too.
They have two things going against them, though: as fruits they're pretty fragile, even more so than other berries; and when they're flowering, they're highly allergenic for a lot of people. Lots of cities actually ban growing mulberry trees within city limits because of the allergy problem.
Of stuff that grows right in my neighborhood in the Bay Area, California, I'd point out passionfruit and prickly-pears as somewhat unusual fruit.
Passionfruit vines like to grow on fences; they make trippy-looking flowers that mature into lemon-sized fruits full of tasty gooey arils around their seeds.
Prickly-pears are Opuntia cactus, which seem to do oddly well here in even rough and windy coastal areas. The same species can also be harvested for the young cactus pads, which are nopales in Spanish; skin 'em and fry 'em up and put 'em in vegetarian tacos.
In Italy we have the chinotto, which is a fruit from the Citrus family that is too bitter to be eaten by itself, but we make a soft drink out of it that is simply perfect.
Technically not my area, but mangosteen. Mostly grown in South-East Asia, it's a sour sweet fruit with the texture and structure like a soft orange, and one big seed per segment. It is seriously delicious.
Loquats are sweet, lightly tart and deliciously juicy. A bit like a very firm peach or plum.
Longyan (dragon eyes) are like lychees but smaller and yellow. They're less sweet than lychees (which tbh I often find a little cloying) and maybe a little more flavourful.
I went to school in Hawai'i and discovered strawberry guava - the plant is an invasive species that chokes the life out of everything it can, but it bears the most delicious fruit.
Check out Taro and Cassava. Taro is a root vegetable similar to arrowroot and has now replaced potatoes for me (except for mash), and I don't even know how to explain cassava, but both are absolutely delicious when boiled with coconut milk/cream.
Macadamia nuts. Not the roasted ones, not the shelled dry ones you can buy in the store. They are garbage compared to the unshelled ones, even if you do need a special device to open them and they can be very frustrating to eat fresh.
When they're freshly opened, they're opaque brighter white, sweet and even a little juicy. It's a completely different experience from the ones you can buy off the shelf. It's honestly a shame Australia doesn't have a bigger market for the fresh ones.
Pakay! Also called ice cream bean. It's a giant bean, inside there's big seeds surrounded in white solid-fluffy stuff. You eat the white stuff. It's sweet without being overpowering and the consistency is interesting. Delicious
Since huckleberries were already mentioned, I'll go for salal berries. Taste like flowery blueberries and make an amazing sauce, especially if you mix them with huckleberries.
Its a tiny little raspberry plant that produces one berry per plant, so its hard to get it in any quantity.
The fruit itself is more juicy than a regular raspberry, and tastes more like fake raspberry flavored candy. Its always a treat to find these while hiking.
I don't see it mentioned so maybe it's not lesser known, but jackfruit is amazing. SEA like most amazing fruit but have seen it more often in North America. Fresh, not the prepped and sauced vegan style.
Do thimbleberries count? Not sure how local they are to me, but they're so tasty. Think a sweeter, more fragile raspberry. They make an excellent jam! my only complaint I have is how fragile they are, they only last a day or two in the fridge
