There is some pricey Amish butter here abouts that I have been wanting to buy.
But I will have to buy it some time when I am in the store without my wife.
She is a real penny pincher when it comes to groceries.
It took me years to get her to pay a little extra for real butter.
She still buys margarine for table use and uses the real butter for cooking.
On rare occasions the real butter is in a dish on the table.
I tried it [a 2#] roll. About $10.00.
And thought it would fit perfectly in the antique butter dish that I use; and cutting a slab; yep it does. BUT the lousy way they have it wrapped, allows the butter to attract an *oh-I've been-in-the-fridge-too-long taste.* Tastes like the inside of a grocery store cooler, as a matter of fact. Spoils the product.
I'm no expert but I think the high-fat content of butter matters. As with ice creams.
Margarine or its ilk, will never darken my refrigerator door, :P
