Y'know how raw tomatoes taste delicious? And how they taste similar to cooked tomatoes?
Now let's talk about chard.
Raw chard is terrible. Urg! So bitter and weird-tasting and fibrous! I put it in my sandwich (just the leafy part) and it was...pretty bad.
So I decided to cook it for a long time in my spaghetti and it was, can you believe it, sweet! I am not kidding. Sweet stems. They were so bitter, throat-burning, and fibrous raw! Now, cooked, they are tender, sweet/mild, and sorta like really baby celery!
It also stains my spaghetti pink, which is cool.
