Another thing I did while helping Kheng in pastry today was making up some cookie dough. This makes LOTS of cookies - 14 x 2.5 lb batches - but can be scaled down.
Mix together:
4 lb butter
4 lb sugar
4 lb brown sugar
Add and mix in:
1 L eggs (20 eggs)
100 mL vanilla
Add and mix in:
44 g baking soda
20 g baking powder
10 g salt
2.3 kg flour
1.6 kg rolled oats
1 box special k
2 kg chocolate chips
I then weighed out 2.5lb chunks, and rolled them into logs for somebody else to cut and bake later.
