So these are biscuits, my mother in law (‘Stan’ – to me) calls them cookies, they are not. Biscuits are short like me, short and sweet. Short in the context of biscuits means the finished biscuit is crisp and crumbly; a cookie tends to be more moist and chewy.
When bringing the dough together you squish it rather then kneed it. When cutting the biscuits out you will then need to bring the trimmings back to a ball to roll out again – more squishing. If you do more than a mere squish you are in effect kneading the dough and the gluten will get going and spoil the crumbly texture. No one wants a heavy biscuit.
