Baking in France: Chocolate Chip Cookies (attempt 1)

 Today was one of my first attempts at baking in France.  I started off with the classic chocolate chip cookie.  Recipe here.  As expected there were some challenges/conversions to be made.

Change #1 butter comes in 250g bars.  1 cup of butter = 227g butter.  Because I do not own a scale (yet) and did not want to estimate 227g, I used the whole 250g butter.

The new laboratory

So far, so good
Change #2.
350°^F is 177°^C.  Of course I misread this and set the oven to 130°^C (266°^F).  The cookies took longer, but otherwise seem unaffected.

The end result:

Observations:

The cookies are good.  No observed change with the addition of 23g of butter. 

Success!
