So this past weekend I encountered a peculiar line in a recipe which I am hoping someone with more cooking knowledge than me can shed light on
Combine flour, brown sugar, and a pinch of salt in another bowl. Using two knives, work cold butter, cut into pieces, into flour mixture until it resembles coarse meal. Sprinkle mixture evenly over blueberries.
What I ended up doing whats putting everything into a pyrex bowl and pathetically hacking at the butter chunks until my wrists hurt. My question is two-fold:
1) Why? I assume the recipe has some justification for why two knives are the appropriate tool.
2) Is there a particular technique one should use when "working" the mixture?
