When looking at several new electric cooktop unit instructions they all say that the "The flexible armored cable extending from the
appliance should be connected directly to the junction box." My question is that since this is a standard residential box that is recessed and flush with the wall, how do you connect it directly to the J-box without an appliance cord and plug?

Standard single gang cover with a hole for the ac cable?

Single or two gang whatever it takes.
 
Yes, A metal single gang cover with a hole for the knockout would work.
How ever that is usually in a bad location. Most people remove the cable from the house outlet box and surface mount a 4'' sq. box some where behind the appliance. In a more accessible location. Assuming of course this appliance is " fastened in place."
You could likely do it in a 100 different ways and still be code compliant.
 
I've never put one in using a flush mount box. It's always been a 4" sq (1900) box in side the cabinet below the cooktop or sometimes the next cabinet over.
Unless the flush mount box is inside the cabinet I think you will have problems having room for the whip.
 
I got the impression the box is already existing and only the unit is new. But if I was roughing for this I would have just left a cable whip out so I could mount a surface box in a good spot later.

Yep, probably already there or roughed in for a stand alone range.

I just roughed in for a cooktop and slide in oven. The spec sheet showed exactly where a JB should be installed for clearance. Including a hole through the cabinet should it need to be in an adjacent cabinet, depending on whether anything would be over the oven that would interfere with clearance.

Yes the box is existing and is single gang inside the wall. Your typical blue residential device junction box. And if we are are nit picking about code would a metal cover with a hole for the whip be ok with a plastic box?

Also the breaker is double 30 amp...looking at one particular cook top unit it calls for a minimum of a 30 amp break, yet the current in the spec sheet is 30.8 amps...Why is a 30 amp breaker ok when the full load current is higher?

There is an adapter, around here we call it a single to foursquare. It mounts to a single gang box and looks like a surface mounted 4S or 1900 box. It has a place to land a ground screw, so no worries about how to bond the cover plus it gives you more room to make up the leads from the cook top.

As far as the spec sheet, if the unit says 30A breaker is all you need then you're good to go.
