Thanks, Bokomoko! I found it!
So, let's sum up:
In case of ENGINE FAILURE IN THE LANDING CONFIGURATION Boeing says: " ...In the event of a go around, maintain VREF+15, retract flaps to position 1 (!) ..."
So that's what I'll do. We know it takes a lot of time for the flaps to move from 30 to one, so no danger of stalling while accelerating while pulling up!
Thanks everybody!
