As Whopity says - SSR at the first stall warning. Whatever it is which construes the first warning!!
Full Power and Control Column centrally forwards whilst maintaining balance until the 'recovery' attitude is attained.
The 'recovery' attitude to maintain is that achieved when whatever gave the stall warning no longer does so. No need to select huge nose down pitch attitudes - as Whopity infers, the pitch attitude may only be a tadge* less than the attitude at which the warning first occurred!
Then - and only then - level wings and recover from any descent.
*tadge = a bit more than a smidge
