I changed and adapted with the times. No more miracle whip! Helmans is the best and used liberally.
No more grating! Buy the cheddar or combo finely pre-grated cheese to your taste. I love either Sharp or the Mexican cheese combo. Life is even easier with diced pimentos in the jar.
I would love to be able to tell you exactly what the proportions are, but it is more done by sight. When using large amounts of cheese like I have done(5 lbs cheese ), use a large or even two small drained jars of chopped pimentos. Always drain. And the question you ask yourself, how much do I like pimentos? Mayo amounts are added so it is not a dry combination, so in a large batch it could be a whole jar of mayo. Add it in chunks so as not to over mayo-nize it!
Salt minimally, dash of pepper still to your liking. And always a pinch of sugar. The pinch should be according to the batch size.
I have added Dill Weed at times. Some like tobacco. I like it most as a purist. If any questions. Ask away! But most of all...enjoy!
