@Val123 Kosher bread would be the same as non-kosher, just the kitchen would meet “kosher standards” and had been blessed/approved by a Rabbi. Lots of the packaged products you eat and drink are kosher you just don’t know to look for it. If it has a small K, P, or U kosher. I just glanced at three products in my pantry all kosher, Sunmaid raisins, Townhouse Flip Crackers, and Quaker Oats instant Oatmeal.
Kosher means you cannot have meat and dairy together, you cannot even use the same plates or cooking pans for meat as you do for dairy, even though you wash them in-between. You would literally need seperate dishwashers if you cooked both in the same kitchen if you really do it the right way. And no shellfish allowed and no pork.
The P stands for Pareve, and it is neutral, so there is no dairy or meet in those items, so you can put that food with either meat or dairy.
