Sweetness doesn't really mean it's fruit. Some fruits/vegetables just have less sugar, or have more acidity than others.
Aye. The quaifier, in general, is that a fruit contains the seeds from which the pant produces excluding nuts, because they have no pulp of any kind. Rhubarb however, is a vegetable.
Leaf, root, or stem, is vegetable.
Is it a male Avocado tree? ...jk
If you grew it from seed it can take 5-10 years (maybe sooner or later depending on variety), but if you bought it at a nursery (usually grafted IIRC) you can get some in 3 at the earliest. Also self-pollination on a single tree is a little tricky, again, depending on variety, but if it flowers you can set the pollen yourself if you can figure out the order it releases pollen. Uhh... I'm a bit hazy on the specifics, so you might want to just look it up if you know what kind of tree it is.
Also beans are fruit.
Man, I can't believe how many people don't like tomatoes...!? I'd really like to know where you guys are getting your tomatoes, seriously.
The texture kills them for me. Again, sauces and soups, fine, but I've never been a fan otherwise.
The potato is the only nightshade plant that I regularly ingest without major alteration (cooking techniques), although I smoke enough tobacco leaf to consider that my primary nightshade consumption. Given my joint infammation, none of that genus is good for me, at all, at all; but I love it all too much.
Not so keen on eggpant, and obviously, I woud ony use true nightshade berries in a very carefully prepared tincture, should I decide to make any again. It's dangerous to prepare it.
