My bad, any 5th mode of Harmonic minor will do. If you do 5th mode in A Harmonic minor you will be playing the V(7) chord in the key of A HM which is and E or an E7. Then one must play the A HM scale over that one chord and you will get that sound I mentioned above.

In the Key of E HM the V(7) chord is obviously B or B7.
