It is always nice to have useful info and here is something I learned about peppers.

Peppers with 3 bumps on the bottom are sweeter and better for eating.
Peppers with 4 bumps on the bottom are firmer and better for cooking.

If you eat a lot of vegetables and fruits do you have some ideas of how to tell the difference between them? I would specially be interested in knowing the difference between mushrooms. Please share your observations in the comment section of the blog.
