I do not care for romaine lettuce at all.
1_Wizard
Why but i like the fact that  it is tolerant of heat,  Unlike most lettuces
0_Apprentice
I just have never cared for romaine lettuce. Something about the taste. I was not aware it was tolerant of heat. Do you know anything else interesting about it?
1_Wizard
What about the milky fluid which gives the romaine the typically fine-bitter herb taste.

I was not aware that is where it got the bitter taste but I think that is what I do not like. I do know that it is the usual lettuce used in Caesar salad. That is about all I know about romaine lettuce.
1_Wizard
Yes that is it. You should pay attention to the  thick ribs, especially on the older outer leaves

What are the thick ribs? Is that where the milky fluid is that gives it that bitter taste?
1_Wizard
Yes that is why it is a common salad green, and is the usual lettuce used in Caesar salad.
