My sole reason for wanting to try rhubarb pie is because of people who've had rhubarb saying how sour it is. I fucking love sour stuff, and celery. So hells yeah I want some rhubarb. I never see it around here though 😬
Its the leaves that have a lot of oxalic acid, the stems are edible raw, just utterly unpalateable. Although if you have a miracle berry first it is apparently delicious - https://youtu.be/hgvRoCY0hNA?t=10m26s
Raw celery is 95% water, 3% carbohydrates, 0.7% protein, and contains negligible fat (table). A 100-gram (3+1⁄2-ounce) reference serving provides 16 calories of food energy, and is a rich source of vitamin K, providing 28% of the Daily Value, with no other micronutrients in significant content (table).
I "peel" celery like how I peel a potato. So basically peel off the stringy part. Then I cut them diagonally or at a 45° angle. I then stir fry them with carrots and string peas and baby corn and shallots with some garlic and salt.
The smell of raw celery makes me nauseous, especially when cut. Cooked in things I find the texture off-putting and tasteless, compounding the unwanted crunch added to something that shouldn't crunch.
cut celery into large chunks, put some olive oil, pop it into the oven and take it back when it starts to char and soft. mix it with mushroom saute (and stir fried beef if not vegetarian)
