Cut a 16 oz block of sharp cheddar cheese into rectangles that will fit into the KitchenAid Shredder Attachment. There should be about 4 rectangles of cheese. Use the fine shredding blade. Shred your cheese into the mixing bowl you will be using until all the cheese is shredded.
Set mixing bowl onto stand mixer.
Add Duke's Mayonnaise to mixing bowl.
Remove the pith membrane and seeds from the Serrano peppers then mince them and add to your mixing bowl.
Cut about 2 slices of onion and finely chop or mince them. You should have about 4 oz from this. Add this into mixing bowl.
Add garlic powder and ground cayenne pepper to mixing bowl.
Drain you diced pimento jar, leaving just a little juice left and add that to the mixing bowl.
Add flex edge beater to stand mixer, set onto low and mix all ingredients for about 1 minute.
Use a silicone spatula to transfer the mixture into a bowl (or airtight container).
Yields about 4 cups. Each serving is about 2 tbsp.
NOTE: Allowing the recipe to marinate overnight before consuming is when it's at its best. But I challenge you to hold out that long! This recipe always gets eaten immediately after making!Store in an airtight container and refrigerate for best practices with leftovers. It should last 3-4 days this way.
