Grandma’s Mustard Sauce

We fixed Grandma’s mustard sauce every time we had ham.  Okay, we rarely had ham, but this was required.  Here’s Ruth Bressler Claycomb’s recipe card in her handwriting.

Mustard Sauce
1/2 bottle French’s mustard (large half)
1 c sugar
2 Tbsp flour (rounded)
Mix above ingredients together.
1/2 c vinegar
1 c boiling water poured over 1 bouillon cube
1/4 c butter
Add liquid to dry ingredients – cook until thick – add butter.

My favorite part of this recipe is the 1/2 bottle of French’s mustard.  Possibly it came in only one size then.  It reminds me of Mom’s dear friend Adj’s recipe for Quick Tamale Pie – the ingredients include 1 15¢ bag Fritos.  That’s about 1 1/2 Fritos at today’s prices.
