40 gm = 1.41 oz
Is there any hope this might help? .....?
After messing about in my laboratory kitchen, I have reached the conclusion that you need approximately
6 level tbsps of flour (to equal 40 gm)
but the butter is beyond me. Roughly 1 and a half ounces...
And these is cheese-eating surrender monkey tablespoons.
Butter is between 2 and 3 tbsps.
I'd be tempted to do 7 level tbsps flour to 3 level tbsps butter.
