Why didn't my ears bloom?

Toast

I followed the Tartine's recipe.

The height of the bread is great, but don't understand why the ears didn't bloom?

Thanks for your time!

Sorry for the delay I was out of town...

What are you looking for in the crumb structure?  (So I can learn also)

Nice oven spring! Seems like it might be a cutting problem? Try slicing at a lower angle next time...don't just come straight down. Maybe try bringing the blade in 30 degrees from horizontal?

Let me know if that does the trick.

P.S. Do you have a crumb shot?

P.S.S Did you find it difficult to work with the dough? 

I always do a low angle cut at about 30 degrees.  Almost always, only 1 or 2 of the ears out of 4 ears bloom.

I did not find it difficult working with the dough, but I don't have anything to compare it with.  I am brand new at making bread.

of the central square, keep the square the same size but extend the lines going a little more down the side.    Great crust color!

You might also want to try a different score pattern.  An initial, or palm leaf pattern.  Palm leaf is like your hand with most of the lines curving from a point, like fingers from the wrist.  

When I look at the crumb, I first look at crust color, then bubble direction, bubbles sizes and the dough between the bubbles.  I look at the overall curves of the crust and imagine the power behind the uplifting of the dough.  There is upward motion but there isn't a mad rush of the dough to expand into the score lines which makes me want to suggest that you get the proofed dough sooner into the oven.  Try scoring just a touch deeper.  And lots of steam!  :)
