I went to the communist grocery mart at Knockturn Alley and purchased a package of Tom Riddle's 90/10 ground Unicorn meat which I squeezed out of a tube into my frying pan. After adding many secret spices from Yaxley's Five-and-Dime I tossed in a tub of green chilies fire roasted by the Dude Who Must Not be Named procured from Macnair's Emporium. Allow to simmer for 10 mins.
Step 2:
Scrambled eggs from Nott's cage only Farm and added more of the special secret spices along with aged Mexican 3-cheese blend from LeStrange Dairy. Cover with the foil of despair until ready to eat.
Step 3:
Re-hydrate and brown potato hash. Season with British malt vinegar from Scorpio's Bazaar while adding more secret spices and Vegaline-Saxon spray for flavor.
Step 4:
Press your scraper into the unicorn tattoo on your right forearm and fling any excess food onto the ceiling while exclaiming: Morsmordre!
