I am trying these for the first time, I have made other types but never bread and butter. The cucs and onions are in the colander draining now!! Good luck!
Here is a recipe from Recipe Goldmine
Bread and Butter Pickles
10 medium cucumbers
3 medium onions
1/4 cup salt
1 cup vinegar
1/2 teaspoon celery seed
1 cup water
1/2 teaspoon mustard seed
3/4 cup granulated sugar
1/4 teaspoon turmeric
Cut cucumbers in thin slices. Slice onions. Combine cucumbers and onions. Add salt and let stand for 2 hours or overnight.
Drain cucumbers and onions. Heat vinegar, water, celery seed, mustard seed, sugar and turmeric to boiling. Add cucumbers and onions. Boil slowly until cucumbers and onions are tender. Pack while hot in jars. Process.
