Narrative:
On departure from jfk runway 31R breezy climb we leveled off at 11;000 as assigned. I was hand flying the aircraft in green data for the departure. Level at 11;000 ft; we got a clearance to go direct rbv and I looked down to verify that the first officer had selected the proper fix. At that moment we encountered wake turbulence and the airplane pitched up. When I looked up; we were going through 11;300 and the first officer called 'altitude'. I immediately pushed the nose down to return to 11;000 ft. About then; departure control asked us about our assigned altitude and we replied '11;000'. By then we were already back to 11;000 and level. Total time above 11;000 was approximately 5-6 seconds. No traffic conflict occurred. Obviously; had the autopilot been engaged; this would not have occurred.
