These were my father's favorite pickles. I've eaten them for almost 50 years, and have often wondered myself. The ingredients are fresh cucumbers, sugar, water, vinegar, salt, dehydrated onion, spices, calcium chloride, turmeric, and yellow 5. It's a sweet and sour pickle, the name American.
From Wikipedia...
Bread-and-butter pickles are a marinated pickle produced with sliced cucumbers in a solution of vinegar, sugar and spices which may be either be processed by canning or simply chilled as refrigerator pickles. The origin of the name and the spread of their popularity in the United States is attributed to Omar and Cora Fanning, a pair of
Illinois cucumber farmers who started selling sweet and sour pickles in the 1920s and filed for the trademark "Fanning's Bread and Butter Pickles" in 1923 (though the recipe and similar ones are probably much older).
[10] The story attached to the name is that the Fannings survived rough years by making the pickles with their surplus of undersized cucumbers and
bartering them with their grocer for staples such as bread and butter.

Cream in coffee is perfect if you just put about 2 tsps - it can overpower the coffee otherwise I think, and taste too rich... I look forward to mine all night I reckon... I use a double espresso, stevia and cream... 
that's why you like them so much.. 
I never used sugar in anything but cooking until I low-carbed and had cream in my coffee... I found a little Stevia in it moves it up to another level...
