I cant stand regular dills....but I will fight for an entire jar of kosher dills
this is the difference
Dill: Dill is the most popular variety of cucumber pickle. Herb dill or dill oil is added to impart a distinctive and refreshing flavor. There are many types of dill pickles, including:
* Genuine Dill - These pickles are made by the slow "processed" method. Dill weed is added to the tanks during the last stage of fermentation or to the jar after fermentation. These pickles usually have a higher lactic acid flavor than other varieties.
* Kosher Dill - In pickle lingo, "kosher" means garlic has been added to the brine. More robust than regular dill pickles, kosher dills are the ultimate accompaniment to an overstuffed deli sandwich.
