Charlotte's Pimento Cheese

1/2 lb. american cheese
1/2 lb. sharp cheddar cheese
Cube and soften at room temperature 

Place in blender and add -
2 T. fresh minced onion
1 sm. jar pimentos (drained) or 1 fresh pimento
4 T. cider vinegar
4 T. sugar
2 T. mayonnaise

Blend until combined.  This is my favorite pimento cheese recipe - thank you Charlotte! 

I have tried blending cheeses in a bowl with tall sides and using a hand blender.  It takes a bit longer but it is less mess!
