I've seen many recipes tell you to mix sugar and butter with medium speed for about 5 minutes. What if i use slower speed and mix it a little bit longer? Will it make a different in the end?
One more thing,when mixing dry ingredients into wet ingredients,Does it really make a difference if i use hand mixer instead of spatula? In VDOs, I've seen most of the baker usually switch to spatula when they have to mix wet and dry goods together but some of them mix both wet and dry goods in stand mixer.
ps. Thank you in advance for those who edit my question so it's grammatically correct and more understandable.
